FS220
2 Phase High Voltage DC Motor Driver IC
General Description
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.
