Product Description

The DRV591VFP 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. 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 130°C to allow for system-level shutdown before the amplifiers internal thermal shutdown circuitry activates. The fault indicators also signal when an over-current event has occurred. If the over-current circuitry is tripped, the DRV591 automatically resets. The PWM switching frequency may be set to 500 or 100kHz depending on system requirements. To eliminate external components, the gain is fixed at approximately 2.3V/V.
