AP1346/1347
Two Coil Fan Motor Predriver
Features
General Description
- Compatible to a Hall element
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.
- Operating voltage (VCC) : 4V to 28V
- Lock shutdown and automatic restart
- Rotation detection (RD) output name as AP1347
- Speed indication output (FG) named as AP1346
- Output current IO=70mA (max)
- Operating temperature (Topr) : -30ºC to +85ºC
- SOP8 package
- Include Thermal Shutdown circuit
Application
- High voltage, high current brushless DC fan
