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: 3.5V~20V
250mA(AVG) output sink current
Building-in protection diode
Operating temperature range: -20°C~85°C
Package: TO-94
Applications
Brushless DC motor
Brushless DC fan
Revolution counting
Speed measurement
