Description

WSH131 is designed to integrate pole independent Hall sensor with output driver together on the same chip. Either North or South magnetic field with sufficient strength will turn the output on (low). In the absence of a magnetic field, output is off (high). The polarity independence allow WSH131 to easily replace reed switches for superior reliability and case of manufacturing.

To improve stability, it includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller and a open-collector output driver capable of sinking up to 20mA current load. The temperature dependent bias increases the supply voltage of the hall plates and adjusts the switching points to the decreasing induction of magnets at higher temperatures. Subsequently, the output can keep switching on/off on more precise switch point regardless to the ambient temperature. WSH131 are rated for operation over temperature range from 40to 125 and voltage ranges from 2.4V to 26V.
