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
