AH1815 Ultra-Low-Sensitivity, Micropower, Omnipolar Hall-Effect Switch

Diodes' AH1815 provides a small and simple contactless switch solution for battery-powered consumer to industrial applications

Image of Diodes' AH1815 Omnipolars Hall Effect SwitchDiodes' AH1815 is an ultra-low-sensitivity, micropower, omnipolar 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 2.5 V to 5.5 V and uses a micropower sleep function to give an average supply current of only 8 μA. 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.
