General Description

The AH9479/80/81 is a single chip solution for driving single coil brushless DC motors.

It combines a motor driver with a high sensitivity Hall sensor, which simplifies the PCB design and makes the fabrication of small-size motors possible.

The AH9480 has an open-drain tachometer output FG that follows the Hall sensor latching output.
