Automotive position proximity sensing ic with thermal protection DIODES AH3280Q-P-A unipolar switch
Product Overview
The DIODES AH3241Q-AH3244Q/AH3280Q-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, these devices operate over a wide supply range of 2.7V to 27V. Key features include a chopper-stabilized architecture, integrated bandgap regulator for temperature compensation, reverse blocking diode with Zener clamp, and built-in thermal protection with auto-restart. These ICs are suitable for applications requiring specific change control, with AEC-Q100 qualification, PPAP capability, and manufacturing in IATF 16949 certified facilities.
