FS319
SINGLE PHASE DC MOTOR DRIVE IC
GENERAL DESCRIPTION
The FS319, a 1-chip composed of hall sensor and output coil drivers, applied to a
single-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 0.3A and
operating voltage range is wide.
Using few external components, FS319, 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.
