3625 AND 3626 POWERHALL® SENSOR/DRIVERS FOR BRUSHLESS DC MOTORS Requiring a minimum of external ponents, 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 mutating logic, a stable voltage regulator, extensive self and system protective functions, and two high-current saturated npn outputs. Both ICs include thermal shutdown, output over-current limiting, and output transient protection/ flyback diodes. The UDN3625M is nominally for 12 V motor applications while the UDN3626M is...
