General Description
The AP1306 fan motor predriver is suited for
two-coil brush-less DC fan. All functions, including
lock shutdown, automatic restart, speed indication
(FG), have been incorporated into one chip. When
the motor is under lock condition, lock shutdown
function turns off the output. When the lock
condition is removed, the IC automatically restarts
and allows DC fan to run. In addition, the FG
function is to indicate the rotation speed.
Application
- High voltage, high current brushless DC fan
