Overview

Data Sheet TWO PHASE DUAL-COIL CMOS SMART FAN MOTOR DRIVER AH9279 General Description The AH9279 is a most advanced fan control and drive Hall IC manufactured by special CMOS process.
This IC consists of voltage reference, Hall sensor, signal amplifier, wave shaping circuit, locked rotor detector, locked rotor protection and restart circuit, output drive circuit, etc.
.
To allow survival in a harsh environment and in consideration of low cost, the AH9279 has been designed with many functions internally, and requires less external components.
When there is no motion for one second, the IC will detect locked rotor conditions, enter protection mode automatically and disable two outputs for fi...
