data sheet tle 6220 gp v2.2 page 200 9 - 11 - 18 6 functional description the tle 6220 gp is an quad - low - side power switch which provides a serial peripheral inte r- face (spi) to con trol the 4 power dmos switches, as well as diagnostic feedback. the power transistors are protected against short to v bb , overload, overtemperature and against ove r- voltage by an active zener clamp. the diagnostic logic recognises a fault condition which c an be read out via the serial diagno s- tic output (so). circuit description power transistor protection functions 9 ) each of the four output stages has its own zener clamp, which causes a voltage limitation at the power transistor when solenoid loads are switched off. the outputs are provided with a current limitation set to a minimum of 3 a. the continuous current for each channel is 1a (all channels on; depending on cooling). each output is protected by embedded protection functions. in the event of an overload or short to supply, the current is internally limited and the corresponding bit combination is set (early warning). if this operation leads to an overtemperature condition, a second protection level (about 170 c) will change the output into a lo w duty cycle pwm (selective thermal shu t- down with restart) to prevent critical chip temperatures. spi signal description cs - chip select. the system microcontroller selects the tle 6220 gp by means of the cs pin. whe never the pin is in a logic low state, data can be transferred from the c and vice versa. cs high to low transition: - diagnostic status information is transferred from the power outputs into the shift regi ster. - serial input data can be clocked in from then on. - so changes from high impedance state to logic high or low state corresponding to the so bits. cs low to high transition: - transfer of si bits from shift register into output buffers - reset of diagnosis register. to avoid any false clocking the serial clock input pin sclk should be logic low state during high to low transition of cs . when cs is in a logi c high state, any signals at the sclk and si pins are ignored and so is forced into a high impedance state. 9 ) the integrated protection functions prevent an ic destruction under fault conditions and may not be used in normal operation or perm a nently .
data sheet tle 6220 gp v2.2 page 200 9 - 11 - 18 7 sclk - serial clock. the system clock pin clocks the internal shift register of the tle 6220 gp. the serial input (si) accepts data into the input shift register on the falling edge of sclk while the serial output (so) shifts diagnostic information out of the shift register on the rising edge of serial clock. it is essential that the sclk pin is in a logic low state whenever chip select cs makes any transition. si - serial input. serial data bits are shifted in at this pin, the most significant bit first. si info r- mation is read in on the falling edge of sclk. input data is latched in the shift register and then transferred to the c ontrol buffer of the output stages. the input data consists of one byte, made up of four control bits and four data bits. the co n- trol word is used to program the device, to operate it in a certain mode as well as providing dia g nostic information (see page 11 ). the four data bits contain the input information for the four channels, and are high active. so - serial output. diagnostic data bits are shifted out serially at this pin, the most significant bit first. so is in a high impedance s tate until the cs pin goes to a logic low state. new dia g- nostic data will appear at the so pin following the rising edge of sclk. reset - reset pin. if the reset pin is in a logic low state, it clears the spi shift registe r and switches all outputs off. an internal pull - up structure is provided on chip. as long as the r e- set pin is low the device is in low quiescent current mode and the supply current is reduced to typ. 20a. output stage control the four outputs of the t le 6220 gp can either be controlled in parallel (in1...in4), or via the s e rial peripheral interface (spi). parallel control a boolean operation (either and or or) is performed on each of the parallel inputs and r e- spective spi data bits, in order to deter mine the states of the respective outputs. the type of boolean operation performed is programmed via the serial interface. the parallel inputs are high or low active depending on the prg pin. if the parallel input pins are not connected (independent of hig h or low activity) it is guaranteed that the outputs 1 to 4 are switched off. prg pin itself is internally pulled up when it is not connected. prg - program pin. prg = high ( v s ): parallel inputs channel 1 to 4 are high active prg = low (gnd): parallel inputs channel 1 to 4 are low active.
data sheet tle 6220 gp v2.2 page 200 9 - 11 - 18 8 serial control of the outputs: spi protocol each output is independently controlled by an output latch and a common reset line, which di s ables all four outputs. the serial input (si) is read on the falling edge of the serial clock. a logic high input 'data bit' turns the respective output channel on, a logic low 'data bit' turns it off. cs must be low whilst shifting all the serial data into the device. a low - to - high transition of cs tran s fers the serial data input bits to the output control buffer. as mentioned above, the serial input byte consists of a 4 bit control word and a 4 bit data word. via the control word, the specific mode of the device is programmable. msb lsb 3 2 1 3 2 1 bits data bits control dddd cccc : serial input byte five specific control words are recognised, having the following functions: no. serial input byte function 1 llll xxxx only 'full diagnosis' performed. no change to ou tput states. 2 hhll xxxx state of four parallel inputs and '1 - bit diagnosis' outputted. 3 hlhl xxxx echo - function of spi; si direct connected to so 4 llhh dddd in1...4 and serial data bits 'or'ed. 'full diagnosis' performed. 5 hhhh dddd in1...4 and serial data bits 'and'ed. 'full diagnosis' performed. note: 'x' means 'don't care', because this bit will be ignored 'd' represents the data bit, either being h (=on) or l (=off) 1. llll xxxx - diagnosis only by clocking in this control byte, it is possible to get pure diagnostic information (two bits per channel) in accordance with figure 1 (page 11 ). the data bits are ignored, so that the state of the outputs are not influenced. this command is only active once unless the next control co m- mand is again "diagnosis only". 2. hhll xxxx - reading back of input, and ?1 - bit diagnosis? if the tle 6220 gp is used as bare die in a hybrid application, it is necessary to know if proper connections exist between the c - port and parallel inputs. by entering ?hhll? as the control word, the first four bits of the so give the state of the parallel inputs, depending on the c signals. by comparing the four in - bits with the corresponding c - port signal, th e nece s- sary connection between the c and the tle 6220 can be verified - i.e. ?read back of the i n- puts?. the second 4 - bit word fed out at the serial output contains ?1 - bit? fault information of the ou t- puts ( h = no fault, l = fault ). in the expression gi ven below for the output byte, ?fx? is the fault bit for channel x. msb lsb in4 in3 in2 in1 f4 f3 f2 f1 : serial output byte

data sheet tle 6220 gp v2.2 page 200 9 - 11 - 18 10 the or - function is the default boolean operation if the device restarts after a reset, or when the supply voltage is switched on for the first time. if the or operation is programmed it is l atched until it is overwritten by the and operation. 5. hhhh dddd - and operation, and ?full diagnosis? with hhhh as the control word, each of the input signals in1...in4 are 'and'ed with the co r- responding data bits (dddd). & output driver in 1...4 serial input, data bits 0...3 the and operation implies that the output can be switched off by the spi data bit input, even if the corresponding parallel input is in the on state. t spi priority for off - state this also implies that the serial input data bit can only switch the output chan nel on if the co r- responding parallel input is in the on state. if the and operation is programmed it is latched until it is overwritten by the or operation. control words beside no. 1 - 5 all control words except those for diag only, read back of inputs, spi echo, will be accepted as an or or an and command with valid data bits depending on the boolean operation which was programmed before. example 1: llhh hllh: or operation between parallel inputs and data bits, i.e channel 1 and 4 will be switched on. the next command is now: lhhh hhlh lhhh as command word has no special meaning but it will be accepted as an or operation and the data bits will be ored with the inputs and the outputs 1,3 and 4 will be switched on. see above: 'if the or operation is prog rammed it is latched until it is overwritten by the and o p eration.' example 2: hhhh llhl means: data bits will be anded with the parallel inputs and the outputs switch a c cordingly. then hllh hhlh is clocked in: and was latched by the command before and i s now valid again by using the hllh command word. so the data bits will be accepted and again anded with the parallel input signals. see above: 'if the and operation is programmed it is latched until it is overwritten by the or o p eration.'
data sheet tle 6220 gp v2.2 page 200 9 - 11 - 18 11 diagnostics fault - fault pin. there is a general fault pin (open drain) which shows a high to low trans i- tion as soon as an error occurs for any one of the four channels. this fault indication can be used to generate a c interrupt. th erefore a ?diagnosis? interrupt routine need only be called after this fault indication. this saves processor time compared to a cyclic reading of the so i n formation. as soon as a fault occurs, the fault information is latched into the diagnosis register. a new e r ror will over - write the old error report. serial data out pin (so) is in a high impedance state when cs is high. if cs receives a low signal, all diagnosis bits can be shifted out serially. the rising edge of cs will reset all error registers. full diagnosis for full diagnosis there are two diagnostic bits per channel configured as shown in figure 1. normal function: the bit combination hh indicates that there is no fault condition, i.e. normal function. overload, short circuit to battery (scb) or overtemperature: hl is set when the current limitation gets active, i.e. there is a overload, short to supply or overtemp erature condition. open load: an open load condition is detected when the drain voltage decreases below 3 v (typ.). lh bit combination is set. short circuit to gnd: if a drain to ground short circuit exists and the drain to ground current e x ceeds 100 a, short to ground is detected and the ll bit combination is set. a definite distinction between open load and short to ground is guaranteed by design. the standard way of obtaining diagnostic information is as follows: clock in serial information into si p in and wait approximately 150 s to allow the outputs to settle. clock in the identical serial information once again - during this process the data co m- ing out at so contains the bit combinations representing the diagnosis conditions as d e- scribed in fi g ure 1. diagnostic serial out (so) hh normal function hl overload, shorted load or overtemperature lh open load ll shorted to ground ch.4 ch.3 ch.2 ch.1 7 6 5 4 3 2 1 0 figure 1: two bits per channel diagnostic feedback
