Description
SL1703SU 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 high sensitivity, using internal sleep-wake logic to maintain stable operation with minimal current consumption. It features CMOS push-pull output and multiple package options, ideal for low-power magnetic sensing applications.
