WSH237 Overview
The WSH237 is an adjustable Hall Effect Switch with magnetic field measure function for on-site calibration. The Hall sensing switching point of the magnetic field is adjustable through the input reference voltage of Vset pin. The output voltage (Vout) turns to high voltage level when the internal voltage (VB) is greater than the reference voltage (Vset).
