The AH3241Q, AH3242Q, AH3243Q, AH3280Q, AH3281Q, and AH3282Q are high voltage, high sensitivity two-wire Hall Effect Unipolar/Latch switch ICs with integrated self-diagnostics and automotive-compliant AEC-Q100 qualification; designed for position and proximity sensing in automotive applications, such as seat and seatbelt buckle, transmission actuator, gear position, wiper,door/trunk closure, etc.
To support a wide range of demanding applications, the AH3241Q, AH3242Q, AH3243Q, AH3280Q, AH3281Q, and AH3282Q are optimized to operate over a supply range of 2.7V to 27V. These
features include a chopper-stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits. For robustness and protection, the device has built-in reverse blocking diode with a Zener clamp on the supply. The built-in thermal protection also shuts down the chip if temperature rises to an abnormal value. This will automatically restart the chip once the junction temperature drops below the safe value. For AH3241Q, AH3242Q, and AH3243Q 2-wire unipolar switches: when the flux density (south pole) exceeds BOP, the supply current state is turned on (low or high). The output is held until a magnetic flux density falls below BRP, causing output current to be turned off. For AH3280Q, AH3281Q, and AH3282Q 2-wire latch switches: when the magnetic flux density is larger than BOP, output current is turned
on (high). The output state is held until a magnetic flux density reversal falls below BRP, causing output current to be turned off (low).
