Product Description
Product Overview
The AH8502 is a micropower linear Hall-effect sensor featuring an 8-bit output resolution. Its output voltage is ratiometric to the supply voltage and proportional to the magnetic flux density. Designed for battery-powered consumer and industrial applications, it offers flexible operating modes (Micropower, Turbo, External-Drive) controlled by a CNTRL pin to optimize power consumption. The device boasts a low typical supply current of 13A in default micropower mode and is available in a compact U-DFN2020-6 package.
