25mA 30V FH130 Hall Effect Latch Sensor

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) with North pole

Functional Description :

FH130 is designed to integrate Hall sensor with output driver together on the same

chip, it is suitable for speed measurement, revolution counting, positioning, and DC

brushless motors. 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.

WSH130 are rated for operation over temperature range from –40˚ C to 125 ˚C and

voltage ranges from 2.4V to 26V.
