General Description
2 Phase High Voltage DC Motor Driver IC
Pb Free
The FS220, a 1-chip composed of hall sensor and output coil drivers, applied to a 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 0.45A and operating voltage range is from 2.8V ~ 28V. Using few external components, FS220, a high performance integrated IC, is designed for a single-phase DC motor circuit. The circuit diagram of the typical application example is as below.
