SA276 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.
SA276 Key Features
- On-chip hall sensor
- Wide operating voltage: 3.5V to 20V
- 400mA (avg) output sink current
- Build-in power-reverse protecting diode only for reverse power
