Compact and simple contactless switch solution for battery-powered applications

Digi-Key now stocks Diodes' AH1815 ultra-low-sensitivity, micro-power, omni-polar Hall-effect switch IC designed for portable and battery-powered consumer equipment, home appliances, and industrial applications. Based on two Hall-effect plates and chopper-stabilized architecture, the AH1815 provides a reliable solution over the whole operating range. It has been optimized to operate over the supply range of 2.5V to 5.5V and uses a micro-power sleep function to give an average supply current of only 8µA. The AH1815 has an open-drain output for flexibility and is now available in a small, low-profile SOT553 and a through-hole SIP-3 package in addition to the industry-standard SC59.
