SL1303SC Hall Effect Sensor SOT-23-3L
SL1303SC is a high‑performance, ultra‑low‑power omnipolar TMR magnetic switch combining advanced TMR (Tunneling Magnetoresistance) and CMOS technology. It detects magnetic fields parallel to the package surface and responds to both N‑pole and S‑pole signals with high sensitivity and stability. Built‑in temperature compensation and clock control ensure reliable operation at minimal power consumption, ideal for battery‑powered and space‑constrained applications.
