2-PHASE DC MOTOR DRIVE IC
GENERAL DESCRIPTION

The FS276, 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 up to 0.45A and operating

voltage range is from 2.8V ~ 20V.

Using few external components, FS276, 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.
