Description
SL1303SE is a high-sensitivity, ultra-low-power TMR (Tunneling Magnetoresistance) omnipolar magnetic switch. It integrates advanced TMR and CMOS technology to detect magnetic fields parallel to the package surface with omnipolar (N/S pole) response. Built-in temperature compensation and sleep-wake logic ensure stable, accurate detection at extremely low power, making it ideal for battery-powered and compact devices.
