High reliability
2-phase half-wave motor pre-driver
BA6409F
Description
The BA6409F is a two-phase half-wave motor pre-
driver for fan motors. The built-in protection diode
eliminates an external diode and the concern of
connecting in reverse when fan motors equipped.
The device also has a lock-up detector and
automatic restart function. There is a lock-up
detector output pin on the IC.
Features
1) Built-in discrete diode for reverse connection
protection. (Maximum reverse connection
protection voltage: 80V)
2) Lock-up detector function & lock-up detector
output pin.
3) Compact SOP8-pin package. Fewer external
components make mounting spaces smaller.
4) Automatic restart when lock-up is removed.
5) Hall element input hysteresis circuit is built-in.
