Pin Assignments
The AH1802 is a high-sensitivity, micropower, omnipolar Hall Effect switch integrated circuit (IC) designed for portable and battery-powered equipment, such as cellular phones, PDAs, and portable PCs. Based on two sensitive Hall Effect plates and a chopper-stabilized architecture, the AH1802 provides a reliable solution over the whole operating range. To support portable and battery-powered equipment, the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µW with a supply of 3V.
