SDC211 - Two-Phase DC Fan Driver

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.
