Description
SL1703AE is a high-performance, ultra-low-power, omnipolar Hall-effect switch designed for compact and battery‑powered systems. It detects both N‑pole and S‑pole magnetic fields with stable sensitivity, using internal wake‑sleep control and temperature compensation to achieve reliable detection with extremely low power consumption. It features open‑drain output and comes in a tiny SOT‑23‑3L package, ideal for portable electronics and low‑power smart devices.
Our Advantages
- Ultra-low power consumption: only 0.9μA at 1.8V, greatly extends battery life
