Anachip AP1307U-SA Two coil fan motor predriver Datasheet

AP1307
Two Coil Fan Motor Predriver
„ Features
„ General Description
- Compatible to a Hall element
- Operating voltage (VCC) : 4V to 28V
- Lock shutdown and automatic restart
- Rotation detection (RD) output
- Output current IO=70mA (max)
- Operating temperature (Topr) : -30ºC to +85ºC
- SOP8 package
- Include Thermal Shutdown circuit
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
