Product Specification
| Description | SOT-23-3 Switches (Solid State) RoHS | Mfr. Part # | AH3712-SA-7 |
| Package | SOT-23-3 | Model Number | AH3712-SA-7 |
The AH3712 is a high-voltage, high-sensitivity Hall-effect latch IC designed for commutation of brushless DC motors, flow meters, linear encoders, and position sensors in industrial and consumer home appliances and personal care applications. It operates over a 3.0V to 27V supply range and features a chopper-stabilized architecture with an internal bandgap regulator for temperature-compensated supply. The device offers an overcurrent limit on its single open-drain output, which switches on with a South pole and off with a North pole of sufficient strength. The output latches until the magnetic flux density reverses below the release point.
