AH276 Overview
AH276 are integrated Hall sensors with output drivers, mainly designed for electronic mutation of brush-less DC Fan. This IC internally includes the regulator, protecting diode, Hall plate, amplifier, parator, and a pair of plementary open-collector outputs (DO, DOB). While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high).
AH276 Key Features

- 400mA (avg) output sink current
- Built-in protecting diode only for chip reverse power connecting
- 20°C to 85°C operating temperature
- Low profile 4 pin SIP package
