SDC277
General Description
Features
The SDC277 is an integrated circuit which includes Hall
Tsensor and output drive circuits.
It’s widely used in
2-phase brushless DC motor and Fan.
It’s composed of
Npower reverse protection circuit, high stable voltage E
regulator, Hall voltage generator, a differential amplifier,
Schmitt trigger and open collector output (DO, DOB).
MIn the case of power supply reverse connecting, the Uinternal protection diode can protect IC but not protect OCcoil, a protection diode can be added if necessary.
Wide operating voltage range: 3.
5V~20V 250mA(AVG) output sink current Building-in protection diode Operating temperature range:...
