Description
TSH253 Hall-effect sensor is a temperature stable, stress-resistant switch. 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. TSH253 includes the following on a single silicon chip: voltage regulator, Hall voltage generator,
small-signal amplifier, chopper stabilization, Schmitt trigger, open-drain output. Advanced CMOS wafer fabrication
processing is used to take advantage of low-voltage requirements, component matching, very low input-offset
errors, and small component geometries.
