Description

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. To support a wide range of demanding applications, the design is optimized to operate over a 3.0V to 27V supply range. With chopper stabilized architecture and an internal bandgap regulator to provide temperature-compensated supply for internal circuits, the AH3712 provides a reliable solution over the whole operating range. The output also has an overcurrent limit.
