SL1703FH Hall Effect Sensor SOT-23-3L
SL1703FH is a high-performance, low-power, high-speed omnipolar Hall-effect switch sensor designed for compact and battery-powered systems. It detects both N-pole and S-pole magnetic fields with high threshold stability, using internal wake‑sleep control and temperature compensation to ensure reliable switching at 500Hz. It features CMOS push‑pull output and comes in a tiny SOT‑23‑3L package, ideal for high‑speed magnetic detection applications.
