SA276 BRUSH-LESS DC-FAN DRIVER WITH ON-CHIP HALL SENSOR DESCRIPTION SA276 mainly designed for electronic commutation of brush-less DC fan. This IC internally includes the Hall Plate, Regulator, Pre-Amplifier, Comparator, and a pair of complementary 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. 1234 TO - 94 FEATURES * On-chip hall sensor * Wide operating voltage: 3.
