document number: 74633 s-80224-rev. c, 04-feb-08 www.vishay.com 5 vishay siliconix SIP42104 timing diagram detailed operational description SIP42104 is an easy to use integrated h-bridge driver and programmable output pulse width controller ic intended for digital camera micro module focus mode applications. the ic is designed to drive a solenoid of several hundred micro-henrys and operates over the supply range of 2.3 to 4.2 v. both h-bridge outpu t can source and sink up to 250 ma. the break-before-make delays prevents shoot-through via m1 to m2 or m3 to m4 in the h-bridge and is guaranteed by design. in the absence of any edge transi tions at the input pin, the ic is in the power-down mode with the h-bridge outputs at high impedance drawing only sub micro-amp of leakage current from the supply. the input pin is cmos logic level and has typical 1.75 a pull-down current, the input pin is buffered by a schmitt trigger with the threshold level of 1.1 v and typical hysteresis of 280 mv. a logic transition closes sw2 and initiates the h-bridge output turn-on for duration set by the external rc time constant. the logic level transition is latched in the device and this logic level transition determines which of the h-bridge output mosfets turns on. if the logic transition is rising from ground to v dd , with the high condition being present for at least 2 s, then m1 and m4 will turn on, m2 and m3 will turn off. this means that out1 will go high and out2 will go low. conversely, a falling logic transition is from v dd to ground, with the low level being present for 2 s, will turn on m2 and m3, m1 and m4 will turn off. once the input transition is latched, SIP42104 will ignore any input spurious transition until the rc pin time out is completed. an internal deglitch filter following the input buffer prevents SIP42104 from being accidentally triggered by the input pulse less than 300 ns duration. a positive edge transition on the input pin also initiates SIP42104 to charge the rc pin to v dd via sw1. this pre-charge period lasts for approximately 30 s. when the pre-charge period is completed, sw1 will turn off and the external capacitor begins to discharge via the external resistor. the timer and pulse width controller sense the voltage on rc pin. when the voltage on the rc pin falls to v1 (0.27 x v dd ). the timer and pulse width controller terminate the timeout and turn off the relevant h-bridge outputs. this yields and ou tput pulse width given by: t output = 1.3 x rc SIP42104 h-bridge output typically drives an inductive load. when output are turned off afte r the rc timeout, the current will still be flowing in the inductive load. to prevent the load current from forward biasing the body diodes of the output mosfets, both h-bridge lo w-side mosfets m2 and m4 will turn on briefly to allow the inductive load current to discharge to zero. when the voltage on the rc pin has fallen to v2 (0.23 x v dd ). this yields a discharge time: t discharge = 0.13 x c x r1 where r1 is the built-in resistor of 1.1 k . following this discharge time period, sw2 and all h-bridge output mosfets are turned off. SIP42104 powers down to its low quiescent current stat e. SIP42104 will remain in this state until the next input transiti on logic applied to the input pin to wake up. figure 4. s s t edge < 100 ns t edge < 100 ns t > 2 s inp u t control logic inp u t control logic o u tp u t c u rrent v out1 t rc = 1.3 x rc v out2 t rc = 1.3 x rc
