The AH1911/AH1921 are ultra-low power digital Omnipolar Hall Effect switch ICs designed for battery-powered consumer products, utility meters, smoke detectors, and IoT devices. Featuring a hibernating clocking system with an average supply current of 1.6A at 3V and a wide supply voltage range of 1.6V to 5.5V, these devices offer extended battery life and design flexibility. Their chopper-stabilized design ensures superior stability over temperature and supply voltage variations, while a high ESD level of up to 6kV enhances system robustness. The AH1911 provides a push-pull output, and the AH1921 offers an open-drain output, both activated by either the North or South pole of a magnet.
