Two-Phase DC Fan Driver with FG
Datasheet
SDC211
General Description
Features
The SDC211 is a chip that is composed of Hall sensor and
Toutput coil drivers, it’s applied to two phase DC motor.
The high sensitivity of Hall effect sensor is suitable for
Nmotors from mini-type CPU coolers to DC fans. Typical
Eoperation current is 250mA and operating voltage range
is wide. FG signal provides a square waveform output for
OCUMthe detection of the motor speed.
Built-in Hall sensor/drivers
Wide operating voltage range: 4.0V~20V
Output sink current up to 250mA
Low quiescent supply current under 5mA
Built-in FG output
Package: TO-94
Applications
Dual coils brushless DC motor
Dual coils brushless DC fan
Revolution counting
Speed measurement
