WSH134
Unipolar Hall Effect Switch IC
Features:
z Operates from 2.4V to 26V supply voltage with reverse voltage protection
z Operates with magnetic fields from DC to 15kHz
z On-chip Hall Sensor
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, and DC
brushless motors
z On (L) with magnetic South pole and Off(H) without magnetic field or with
magnetic North pole
Functional Description :
WSH134 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 output can keep switching on/off on more precise
switch point regardless to the ambient temperature. WSH134 are rated for operation
over temperature range from –40˚ C to 125 ˚C and voltage ranges from 2.4V to 26V.
