General Description
The AP1346/7 fan motor predriver is suited for
two-coil brush-less DC fan. All functions, including
lock shutdown, automatic restart, speed indication
(FG), have been integrated 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 and the RD
function is to detect the motor status.
