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.
