Operates from 2.4V to 26V supply voltage with reverse voltage protection
Operates with magnetic fields from DC to 15kHz
On-chip Hall Sensor
On-chip temperature compensation circuitry minimizes shifts in on and off points
and hysteresis over temperature and supply voltage
Ideal sensor for speed measurement, revolution counting, positioning, and DC

Functional Description :
WSH130NL is designed to integrate Hall sensor with output driver together on the
same chip, it is suitable for speed measurement, revolution counting, positioning. 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. An on-chip protection resistor is implemented to prevent reverse
power fault.
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 open collector output switches to the appropriate state.
WSH130NL are rated for operation over temperature range from ­40° C to 125 °C
and voltage ranges from 2.4V to 26V.
