Texas Instruments DRV592

the drv592 is a high-efficiency high-current h-bridge ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 v to 5.5 v. low output stage on-resistance significantly decreases power dissipation in the amplifier. the drv592 may be driven from any external pwm generator such as a dsp a microcontroller or a fpga. the frequency may vary from dc (i.e. on or off) to 1 mhz. the inputs are compatible with ttl logic levels. the drv592 is internally protected against thermal and current overloads. logic-level fault indicators signal when the junction temperature has reached approximately 130c to allow for system-level shutdown before the amplifiers internal thermal shutdown circuitry activates. view all in datasheet
