3625, POWERHALL SENSOR/DRIVERS FOR BRUSHLESS DC MOTORS

3625 AND 3626 POWERHALL® SENSOR/DRIVERS FOR BRUSHLESS DC MOTORS Requiring a minimum of external components, the UDN3625M and UDN3626M are monolithic ICs that provide single-chip control and direct drive solutions for many small, single-phase, unipolar brushless dc motor applications.

Integrated into the ICs are a highsensitivity Hall-effect sensor, control and commutating logic, a stable voltage regulator, extensive self and system protective functions, and two high-current saturated npn output
