DRV592VFP

The DRV592VFP is a high-efficiency high-current H-Bridge Driver ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 to 5.5V and requires external PWM. Low output stage on-resistance significantly decreases power dissipation in the amplifier. The DRV592VFP may be driven from any external PWM generator such as a DSP, a microcontroller or a FPGA. The frequency may vary from DC (i.e., on or off) to 1MHz. The inputs are compatible with TTL logic levels. The DRV592VFP 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 amplifier's 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 DRV592 automatically resets.
