WSH231 Datasheet, PDF (1/5 Pages) Winson Semiconductor Corp. – Operates from 2.4V to 26V supply voltage with reverse voltage protection

WSH231
North and South pole Two outputs Hall Effect Switch IC
Features:
 Operates from 2.4V to 26V supply voltage with reverse voltage protection
 Operates with magnetic fields from DC to 15kHz
 On-chip Hall Sensor and driver
 On-chip temperature compensation circuitry minimizes shifts in On/Off
points temperature and supply voltage
 Wide range operating temperature –40 ~ 90℃
 Output1: On (L) with magnetic South pole
Output2: On (L) with magnetic North pole
Both Off(H) without magnetic field
Functional Description:
WSH231 is the Hall sensor which designed to separate South pole and North
pole switch with two different outputs that drive together on the same chip.
South magnetic field with sufficient strength will turn the output1 on (low), the
same reaction will be found in output2 for North magnetic field. In the absence
of a magnetic field, both two outputs are off (high). The separation output of
North and South pole allows WSH231 to easily interpret the direction of
magnetic field. It can be widely used, like replace reed switches for superior
reliability and case of manufacturing.
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. WSH231 are
rated for operation over temperature range from –40˚ C to 90 ˚C and voltage
ranges from 2.4V to 26V.
