W W W .O 1ROI2CHE23112NT-CHIP.COM OCH211 2-Phase DC Motor Drive IC With FG Output ◼ General Description The OCH211, a one-chip composed of hall sensor and output coil drivers, applied to 2-phase DC motor. The high sensitivity of Hall effect sensor is suitable for motors from mini-type CPU coolers to blowers and DC fans. Typical operation current is 0.4A and operating voltage range is wide. FG signal, an open collector, provides a square waveform output for the detection of the motor speed. Using few external components, OCH211, a high performance integrated IC, is designed for a 2-phase DC motor circuit. The circuit diagram of the typical application example is as below. OCH211 is available in SIP-4L package and is rated over the -40°C to 125°C.
