Switch Hall IC

SDC277

General Description

Features

The SDC277 is an integrated circuit which includes Hall

sensor and output drive circuits. It’s widely used in

2-phase brushless DC motor and Fan. It’s composed of

power reverse protection circuit, high stable voltage

regulator, Hall voltage generator, a differential amplifier,

Schmitt trigger and open collector output (DO, DOB).



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

In the case of power supply reverse connecting, the

internal protection diode can protect IC but not protect

coil, a protection diode can be added if necessary.
