The TSH193 is a temperature stable, and stress-resistant Hall-effect sensor.
Superior high-temperature performance is possible through dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage that can be caused by device over molding, temperature dependencies, and thermal stress.
The TSH193 includes the following on a single silicon chip: a voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and output pull-up resistor on a single silicon chip. 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 is on, and only switches off when a north polarity field of sufficient strength is present.
TSH193 comes in TO-92S and SOT-23 packages.
