Description

TSH188 Hall-effect sensor is a temperature stable, stress-resistant sensor. Superior high-temperature

performance is made possible through a dynamic offset cancellation that utilizes chopper-stabilization. This

method reduces the offset voltage normally caused by device over molding, temperature dependencies, and

thermal stress. TSH188 includes the following on a single silicon chip: voltage regulator, Hall voltage generator,

small-signal amplifier, chopper stabilization, Schmitt trigger. Advanced DMOS wafer fabrication processing is used

to take advantage of low-voltage requirements, component matching, very low input-offset errors, and small

component geometries. This device requires the presence of both south and north polarity magnetic fields for

operation. In the presence of a south polarity field of sufficient strength, the device output sensor on, and only

switches off when a north polarity field of sufficient strength is present
