AH32x Two-Wire Hall Effect Unipolar/Latch Switches

Diodes Incorporated AH32x Two-Wire Hall Effect Unipolar/Latch Switches are high voltage, high sensitivity two-wire Hall effect ICs designed for various applications. These switches feature built-in thermal protection that shuts down the chip if the temperature rises to an abnormal value. The chip automatically restarts once the junction temperature drops below the safe value. The AH32x switches feature a chopper-stabilized architecture and an internal bandgap regulator to provide a temperature-compensated supply for internal circuits. These ICs feature a built-in reverse-blocking diode with a zener clamp on the supply for robustness and protection. The AH32x switches operate at 2.7V to 27V supply voltage range and -40°C to 150°C temperature range. Typical applications include position and proximity sensing in automotive applications, seat position, seatbelt buckle, wiper position, window lifter, and gear selection position.
