DRV591 - High-Efficiency PWM Power Driver

Description

The DRV591 is a high-efficiency, high-current power amplifier ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 V to 5.5 V.

PWM operation and low output stage on-resistance significantly decrease power dissipation in the amplifier.

Features

  • D ±3-A Maximum Output Current D Low Supply Voltage Operation: 2.8 V to 5.5 V D High Efficiency Generates Less Heat D Over-Current and Thermal Protection D Fault Indicators for Over-Current, Thermal and Under-Voltage Conditions D Two Selectable Switching Frequencies D Internal or External Clock Sync D PWM Scheme Optimized for EMI D 9×9 mm PowerPAD Quad Flatpack.
