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.
On-chip hall sensor
Wide operating voltage: 3.5V to 20V
300mA (avg) output sink current
Build-in power-reverse protecting diode only for reverse power connecting
