Switch Hall IC
Datasheet
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 Eregulator, 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.
