The AH173-PG-B-B is an integrated circuit Hall Effect/Magnetic Sensor from Diodes Incorporated, specifically designed for board mounting. It is a Hall effect latch switch ICs with built-in bi-stable operation for 3-20V, 25mA supply. This Hall effect/magnetic sensor IC outputs a digital signal in response to a magnetic field, providing a robust digital switch with reliable operation in a wide range of temperatures and environments. With a low power consumption, high-sensitivity level, and low threshold, the AH173-PG-B-B is perfectly designed for applications such as hard disk drive position sensing, security systems, motor speed measurement, and more.
