WSH1132
Unipolar Hall Effect Switch IC
Features:
z Operates from 2.4V to 20V supply voltage
z Operates with magnetic fields from DC to 15kHz
z On-chip Hall Sensor and pull-high resistor
z On-chip temperature compensation circuitry minimizes shifts in on and off points
and hysteresis over temperature and supply voltage
z Ideal sensor for speed measurement, revolution counting, positioning
z Off (High) with magnetic North pole and On (Low) without magnetic field or
with magnetic South pole
Functional Description :
WSH1132 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 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 output can keep switching on/off on more precise
switch point regardless to the ambient temperature. WSH1132 are rated for
operation over temperature range from –20˚ C to 125 ˚C and voltage ranges from
2.4V to 20V.
