General Description
The AP1307 fan motor predriver is suited for
two-coil brush-less DC fan. All functions, including
lock shutdown, automatic restart, rotation detection
(RD), have been incorporated into one chip. When
the motor is under lock condition, lock shutdown
function turns off the output current. When the lock
condition is removed, the IC automatically restarts
and allows DC fan to run. In addition, the RD
function is to detect the motor status.
Application
- High voltage, high current brushless DC fan
