DRV592 - Texas Instruments

DRV592 High-Efficiency H-Bridge

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 f.
