Switch Hall IC
Datasheet
SDC177
General Description
Features
The SDC177 is a latching switch Hall IC. It’s composed of
Tpower reverse protection circuit, high stable voltage
regulator, Hall voltage generator, a differential amplifier,
NSchmitt trigger and open collector output. Change of
Emagnetic field can be converted into digital signal. It can
be used for brushless DC motors, brushless DC fans, and
CUMspeed measurement.
3.5V~20V operating voltage
Built-in temperature compensation circuit
Open collector output
25mA(MAX) output current
Package: TO-92S
Applications
Brushless DC motor
Brushless DC fan
Speed measurement
CONFIDENTIAL DOTO-92S
