SDC211
SDC211 is Two-Phase DC Fan Driver manufactured by SDC.
Description
Features
The SDC211 is a chip that is posed 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 250m A and operating voltage range is wide. FG signal provides a square waveform output for
OCUMthe detection of the motor speed.
