Datasheet Summary
BRUSH-LESS DC-FAN DRIVER WITH ON-CHIP HALL SENSOR
DESCRIPTION
SA276 mainly designed for electronic mutation of brush-less DC fan. This IC internally includes the Hall Plate, Regulator, Pre-Amplifier, parator, and a pair of plementary open-collector Outputs (DO, DOB).
SA276 internally includes power-reverse protecting diode, the protecting diode only protects chips but not for coils. If necessary, add one external diode to block the reverse current from coils.
