DRV591 高效 PWM 功率驱动器

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.

The DRV591 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 DRV591 automatically resets (see application information section for more details)
