Product Overview

The DRV593VFPR is a high-efficiency high-current Power Amplifier ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 to 5.5V. 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. It is 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. The fault indicators also signal when an overcurrent event has occurred. If the overcurrent circuitry is tripped, the devices automatically reset. The PWM switching frequency may be set to 500 or 100kHz depending on system requirements.
