3-phase full-wave fan motor driver IC
BA6425FS
Description
BA6425FS is a 3-phase full-wave fan motor driver IC.
Noise generated by the motor can be reduced by
linear driving system. Forward/reverse rotation
can be switched. This IC has current limit circuit
and FG output.
Features
1) Linear driving system
2) Forward/reverse select switch
3) Built-in current limiter and thermal shut down
4) FG output
