The AH5771-PG-B is a single-phase Hall effect latch smart fan motor controller designed for brushless DC motor applications. It features an integrated Hall sensor, a built-in amplifier for Hall voltage, and a full bridge driver for current load management. The device operates within a supply voltage range of 2.5V to 15V and is capable of handling peak output currents of up to 400mA. It includes rotor lock protection with automatic self-restart functionality to prevent damage when the rotor is blocked. The AH5771-PG-B is housed in a low-profile SIP-4L package and is compliant with RoHS standards, utilizing a "Green" molding compound. It operates effectively across a temperature range of -40¬8C to 100¬8C, making it suitable for various environmental conditions. The device simplifies circuit design by eliminating the need for external timing capacitors, thus reducing the number of external components required.
