description l99pm62xp 12/98 doc id 16363 rev 4 2 description 2.1 voltage regulators the l99pm62xp contains 2 independent and fully protected low drop voltage regulators, which are designed for very fast transient response and do not require electrolytic output capacitors for stability. the output voltage is stable with ceramic load capacitors > 220 nf. 2.1.1 voltage regulator: v 1 the v 1 voltage regulator provides 5 v supply voltage and up to 250 ma continuous load current and is mainly intended for supply of the system microcontroller. the v 1 regulator is embedded in the power management and fail-safe functionality of the device and operates according to the selected operating mode. it can be used to supply the internal hs can transceiver via the cansup pin externally. in case of a short circuit condition on the can bus, the output current of the transmitter is limited to 100 ma and the transceiver is turned off in order to ensure continued supply of the microcontroller. in addition the regulator v 1 drives the l99pm62xp internal 5 v loads. the voltage regulator is protected against overload and overtemperature. an external reverse current protection has to be provided by the application circuitry to prevent the input capacitor from being discharged by negative transients or low input voltage. the output voltage precision is better than +/- 2% (incl. temperature drift and line-/load regulation) in active mode; respectively +/- 3% during low current operation (i. e. in v 1 standby mode). current limitation of the regulator ensures fast charge of external bypass capacitors. the output voltage is stable for ceramic load capacitors > 220 nf. if the device temperature exceeds the tsd1 threshold, all outputs (outx, relx, v 2 , lin) is deactivated except v 1 . hence the micro controller has the possibility for interaction or error logging. in case of exceeding tsd2 threshold (tsd2>tsd1), also v 1 is deactivated (see state chart in chapter 3: protection and diagnosis ). a timer is started and the voltage regulator is deactivated for t tsd = 1sec. during this time, all other wakeup sources (can, lin, wu1 to3 and wake up of c by timer) are disabled. after 1 sec, the voltage regulator tries to restart automatically. if the restart fails 7 times, within one minute, without clearing and thermal shutdown condition still exists, the l99pm62xp enters the forced v bat standby mode. in case of short to gnd at ?v 1 ? after initial turn on (v 1 < 2v for at least 4ms) the l99pm62xp enters the forced v bat standby mode. reactivation (wake-up) of the device can be achieved with signals from can, lin, wu1..3 or periodic wake by timer (see section 2.2.8: timer interrupt / wake-up of microcontroller by timer ). 2.1.2 voltage regulator: v 2 the voltage regulator v 2 can supply additional 5 v loads (e.g. logic components or the integrated hs can transceiver or external loads such as sensors or potentiometers). the

description l99pm62xp 18/98 doc id 16363 rev 4 2.2.4 v bat standby mode the transition from active mode to v bat standby mode is initiated by an spi command. in v bat standby mode, the v 1 voltage regulator, relay outputs, lin and can transmitters are switched off. high-side outputs and the v 2 regulator remain in the configuration programmed prior to the standby command. in v bat standby mode the current consumption of the l99pm62xp is reduced to a minimum level. note: inputs txdl, txdc and csn must be terminated to gnd in v bat standby to achieve minimum standby current. this can be achieved with the internal esd protection diodes of the microcontroller (microcontroller is not supplied in this mode; v 1 is pulled to gnd). 2.2.5 wake up from standby modes a wake-up from standby mode switches the device to active mode. this can be initiated by one or more of the following events: to prevent the system from a deadlock condition (no wake up possible) a configuration where the periodic timer interrupt and wake up by lin and hs can are disabled, is not allowed. the default configuration is entered for all wake-up sources in case of such an invalid setting. all wake-up events from v 1 standby mode (except i v1 > i cmp ) are indicated to the microcontroller by a low-pulse at rxdl/nint (duration: 56 s). wake-up from v 1 standby by spi access might be used to check the interrupt service handler. table 3. wake up sources wake up source description lin bus activity can be disabled by spi can bus activity can be disabled by spi level change of wu1 - 3 can be individually configured or disabled by spi i v1 > i cmp device remains in v 1 standby mode but watchdog is enabled (if i cmp = 0) and the v 1 regulator goes into high current mode (increased current consumption). no interrupt is generated. timer interrupt / wake up of c by timer programmable by spi ?v 1 standby mode: device wakes up and interrupt signal is generated at rxdl/nint when programmable timeout has elapsed ?v bat standby mode: device wakes up, v 1 regulator is turned on and nreset signal is generated when programmable timeout has elapsed spi access always active (except in v bat standby mode) wake up event: csn is low and first rising edge on clk
l99pm62xp description doc id 16363 rev 4 19/98 2.2.6 wake-up inputs the de-bounced digital inputs wu1 to wu3 can be used to wake up the l99pm62xp from standby modes. these inputs are sensitive to any level transition (positive and negative edge) for static contact monitoring, a filter time of 64 s is implemented at wu1-3. the filter is started when the input voltage passes the specified threshold. in addition to the continuous sensing (static contact monitoring) at the wake up inputs, a cyclic sense functionality is implemented. this feature allows periodical activation of the wake-up inputs to read the status of the external contacts. the periodical activation can be linked to timer1 or timer2 (see section 2.2.7: cyclic contact supply ). the input signal is filtered with a filter time of 16 s after a programmable delay (80 s or 800 s) according to the configured timer on-time. a wake-up is processed if the status has changed versus the previous cycle. the outputs out_hs and out1-4 can be used to supply the external contacts with the timer setting according to the cyclic monitoring of the wake-up inputs. if the wake-up inputs are configured for cyclic sense mode the input filter timing and input filter delay ( wux_filt in control register 2) must correspond to the setting of the high-side output which supplies the external contact switches (outx in control register 0). in standby mode, the inputs wu1-3 are spi configurable for pull-up or pull-down current source configuration according to the setup of the external. in active mode the inputs have a pull down resistor. in active mode, the input status can be read by spi (status register 2). static sense should be configured (control register 2) before the read operation is started (in cyclic sense configuration, the input status is updated according to the cyclic sense timing; therefore, reading the input status in this mode may not reflect the actual status). 2.2.7 cyclic contact supply in v 1 standby and v bat standby modes, any high-side driver output (out1..4, ouths) can be used to periodically supply external contacts. the timing is selectable by spi timer 1: period is xs. the on-time is 10 ms resp. 20 ms: with x {1, 2, 3, 4 s} timer 2: period is x ms. the on- time is 100 s resp. 1ms: with x {10, 20, 50, 200 ms} 2.2.8 timer interrupt / wake-up of microcontroller by timer during standby modes the cyclic wake up feature, configured via spi, allows waking up the c after a programmable timeout according to timer1 or timer2. from v 1 standby mode, the l99pm62xp wakes up (after the selected timer has elapsed) and sends an interrupt signal (via rxdl/nint pin) to the c. the device enters active mode and the watchdog is started with a long open window. the microcontroller can send the device back into v 1 standby after finishing its tasks. from v bat standby mode, the l99pm62xp wakes up (after the selected timer has elapsed), turns on the v 1 regulator and provides an nreset signal to the c. the device enters active mode and the watchdog is started with a long open window. the microcontroller can send the device back into v bat standby after finishing its tasks.

description l99pm62xp 22/98 doc id 16363 rev 4 after power-on or standby mode, the watchdog is started with a long open window (65 ms nominal). the long open window allows the micro controller to run its own setup and then to trigger the watchdog via the spi. the trigger is processed when the csn input becomes high after the transmission of the spi word. writing ?1? to the watchdog trigger bit terminates the long open window and start the window watchdog (the timing is programmable by spi). subsequently, the micro controller has to serve the watchdog by alternating the watchdog trigger bit within the safe trigger area (refer to figure 27 ). a correct watchdog trigger signal is immediately start the next cycle. after 8 watchdog failures in sequence, the v 1 regulator is switched off for 200ms. if subsequently, 7 additional watchdog failures occur, the v 1 regulator is completely turned off and the device goes into v bat standby mode until a wakeup occurs. in case of a watchdog failure, the outputs (relx, outx, v 2 ) are switched off and the device enters fail-safe mode (i. e. all control registers are set to default values except the ?out3 control bit?). the following diagrams illustrate the watchdog behavior of the l99pm62. the diagrams are split into 3 parts. first diagram shows the functional behavior of the watchdog without any error. the second diagram covers the behavior covering all the error conditions, which can affect the watchdog behavior. third diagram shows the transition in and out of flash mode. all 3 diagrams can be overlapped to get all the possible state transitions under all circumstances. for a better readability, they were split in normal operating, operating with errors and flash mode. figure 9. watchdog in normal operating mode (no errors) :' 2)) orqj rshq zlqgrz :lqgrz 0rgh sursshuwuljjhulq :lqgrzprgh 75,* ?

description l99pm62xp 34/98 doc id 16363 rev 4 pulses are counted within one frame the complete frame is ignored. this safety function is implemented to avoid an activation of the output stages by a wrong communication frame. note: due to this safety functionality a daisy chaining of spi is not possible. instead, a parallel operation of the spi bus by controlling the csn signal of the connected ic's is recommended. serial data out (do) the data output driver is activated by a logical low level at the csn input and goes from high impedance to a low or high level depending on the global error flag (fault condition). the first rising edge of the clk input after a high to low transition of the csn pin transfers the content of the selected status register into the data out shift register. each subsequent falling edge of the clk shifts the next bit out. serial clock (clk) the clk input is used to synchronize the input and output serial bit streams. the data input (di) is sampled at the rising edge of the clk and the data output (do) changes with the falling edge of the clk signal. the spi can be driven with a clk frequency up to 1mhz.
