FS277 - Feeling Technology

FS277 2 Phase High Voltage DC Motor Driver

The FS277, 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 0.4A and operating voltage range is from 3.0V ~ 20V. Using few external components, FS277, a high performance inte.
