AH3712中文资料27V Open-Drain Hall Effect Latch数据手册Diodes规格书

描述 Description

The DIODES™ 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.

The single open-drain output can be switched on with a South pole of sufficient strength and switched off with a North pole of sufficient strength. When the magnetic-flux density (B) perpendicular to the package is larger than the operate point (BOP), the output is switched on (pulled low). The output is held and latched until magnetic-flux density reverses and becomes lower than the release point (BRP).
