General Description

The DRV593 and DRV594 are high-efficiency, high-current power amplifiers ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 V to 5.5 V.

The operation of the device requires only one inductor and capacitor for the output filter, saving significant printed-circuit board area.

Pulse-width modulation (PWM) operation and low output stage on-resistance significantly decrease power dissipation in the amplifier.
