Overview

Data Sheet Single Phase Low Noise Smart Motor Driver AH9479/80/81 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.
The AH9481 has an open-drain rotation detection output RD that is active low when the motor is spinning and goes high when blocked.
When there is no motion about 0.
4 second, the IC will automatically detect the locked rotor conditions, and enter protection mode, shutting of...
