SL1303TB Hall Effect Sensor SOT-23-3L
SL1303TB is a high‑performance, continuous‑operating TMR (Tunneling Magnetoresistance) omnipolar magnetic switch. It integrates advanced TMR technology and CMOS circuitry to provide real‑time, stable magnetic detection for industrial and consumer electronics. It senses magnetic fields parallel to the package surface and responds to both N‑pole and S‑pole excitation, supporting uninterrupted operation while maintaining low power consumption.
