Description

The DRV593 and DRV594 are high-efficiency, high-currentpower 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.

The DRV593 and DRV594 are internally protected against thermal and current overloads. Logic-level fault indicators signal when the junction temperature has reached approximately 128°C to allow for system-level shutdown before the amplifier's internal thermal shutdown circuitry activates.
