The AH1912 is an ultra-low power digital Omni-polar Hall Effect switch IC designed for battery-powered consumer products, utility meters, smoke detectors, and IoT devices. Its hibernating clocking system ensures an average supply current of only 1.6A at 3V. The wide supply voltage range (1.6V to 5.5V) enhances battery life and supports low-voltage microcontrollers. Featuring advanced chopper stabilization for superior temperature and supply voltage stability, and high ESD protection up to 6kV, the AH1912 is activated by either a north or south magnetic pole. It is available in industry-standard SC59 and X1-DFN1216-4 packages.
