WSH315

Linear Hall Effect Sensor IC

Features:

 Wide operating range 3.0~12V, -40℃~125℃

 Flat Response to 23kHz

 High Sensitivity 1.5 mV/Gauss

 Wide output voltage range 0.2~4.8V (at Vdd=5V)

 Low temperature drift ± 0.2 mV/℃

 Wide sensible magnetic field range on different supplied voltage

±1,500 Gauss on 5V supplied voltage

±3,000 Gauss on 12V supplied voltage. Low operating current 3mA

 Two package styles TO-92S/SOT-23 available.

Functional Description :

The WSH315 is a new version of WSH135 with better measuring range

and thermal shift. It integrates Hall sensing element, linear amplifer, sensitivity

controller and emitter follower output stage.It accurately tracks extremely small

change in magnetic flux density –generally too small to operate Hall effect

switch.

W315 can be applied as current sensor, tooth sensor, proximity detectors

and motion detectors. As sensitive monitor of magnetic flux, it can effectively

measure a system’s performance with negligible system loading while

providing isolation from contaminated and electrically noisy environments.

1. All output-voltage measurements are made with a voltmeter having an input impedance of at least 100kΩ

2. Do not apply any load on output pin, it will degrade IC’s performance.
