2002 sep 27 6 philips semiconductors product speci?cation full bridge driver ic uba2030t functional description supply voltage the uba2030t is powered by a single supply voltage connected to the hv pin (the full bridge supply could be used, for example). the ic generates its own low voltage supply for driving the internal circuitry and the mosfets in the full bridge, removing the need for an additional low voltage supply. a capacitor must be connected between the v dd pin and sgnd to obtain a ripple-free internal supply voltage. start-up when the power is turned on, the uba2030t enters a start-up phase; the high side mosfets are switched off and the low side mosfets switched on. during start-up, the bootstrap capacitors are charged and the bridge output current is zero. oscillation at the point where the supply voltage at the hv pin crosses the start oscillating threshold, the bridge begins commutating between the following two defined states: higher left and lower right mosfets on and higher right and lower left mosfets off higher left and lower right mosfets off and higher right and lower left mosfets on. when the internal oscillator is used, the bridge commutating frequency is determined by the values of an external resistor and capacitor. in this mode, the exo pin must be connected to sgnd. when an external oscillator is used, its output must be connected to the exo pin; the internal oscillator must be disabled by connecting the rc pin to sgnd. the bridge commutating frequency is half the oscillator frequency due to a ? 2 circuit which guarantees an accurate 50% duty factor. the time between turning off the conducting pair of mosfets and turning on the other pair, the dead time, can be adjusted using an external resistor. if the supply voltage at the hv pin falls below the stop oscillating threshold, the uba2030t re-enters the start-up phase. bridge enable the bridge enable function allows the bridge to be held in its current state. when active, it connects the rc pin to sgnd, disabling the internal oscillator. if the bridge enable function is activated during dead time, the bridge is allowed to enter the next conducting state before being held. oscillations resume the instant the bridge enable function is turned off. a timing diagram is shown in fig.3. to hold the bridge, an external control circuit is required to provide a source current to the bridge enable control input (pin be), and to supply a reference voltage to pin ber (see fig.6). shut-down the active high shut-down input (pin sd) can be used at any time to turn off all four mosfets. however, if the supply voltage drops below the stop oscillating threshold, the bridge re-enters the start-up phase even if the shut-down function is active.

2002 sep 27 15 philips semiconductors product speci?cation full bridge driver ic uba2030t additional application information the uba2030t is the commutator part in a complete system for driving an hid lamp. the life of the hid lamp can depend on the amount of sodium that migrates through its quartz wall. to minimize this migration, the lamp must be operated negative with respect to system ground. figure 7 shows a full bridge with an hid lamp in a typical automotive configuration using a control unit referenced to the high side of the bridge. pin ber is connected to system ground. the bridge can be held in its current state by pin be. the supply current to the internal low voltage circuit is fed to pin hv which can be connected to either system ground or to a low voltage dc supply, such as a battery, as indicated by the dotted lines in fig.7. the diode in series with the supply to pin hv prevents c i being discharged if the lamp is shorted during the ignition phase. c6 should be positioned as close as possible to pin dtc. the control unit drives the mosfets relatively hard which can cause radiation. to prevent switching the mosfets hard, a resistor can be connected in series with each gate. in all applications, the voltage on pin hv must not be allowed to become lower than the voltage at pin v dd during the start-up phase or during normal operation, otherwise the full bridge will not operate correctly. during the start-up phase, pin exo and pin sd should both be low. the voltage as a function of time at pin exo and pin sd should be >5 v/ms. fig.7 automotive configuration (example 2). handbook, full pagewidth uba2030t shr ghr fsr v dd sgnd hv exo sd dtc shl ghl fsl pgnd glr ber be rc gll 13 14 15 18 20 21 22 23 24 12 11 10 8 7 5 3 2 1 ignitor lamp c i c i c3 c6 r dt c2 c4 c1 ll hl c5 lr hr high voltage - 570 v (max) system ground control unit from low voltage dc supply c osc r osc mgl763 c1 = 150 nf. c2 = 150 nf. c3 = 220 nf. c6 = 100 pf. c osc =10nf. r osc = 147 k w. r dt =50to1000k w (220 k w results in a dead time of 1 m s).

2002 sep 27 17 philips semiconductors product speci?cation full bridge driver ic uba2030t soldering introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 220 c for thick/large packages, and below 235 c for small/thin packages. wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
2002 sep 27 18 philips semiconductors product speci?cation full bridge driver ic uba2030t suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales office. 2. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 3. these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 5. wave soldering is suitable for lqfp, tqfp and qfp packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. wave soldering is suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package (1) soldering method wave reflow (2) bga, lbga, lfbga, sqfp, tfbga, vfbga not suitable suitable hbcc, hbga, hlqfp, hsqfp, hsop, htqfp, htssop, hvqfn, hvson, sms not suitable (3) suitable plcc (4) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (4)(5) suitable ssop, tssop, vso not recommended (6) suitable
