TSH188 Ultra High Sensitivity Hall Effect Latch TO-92S Pin Definition: 1. VCC 2. GND 3. Output SOT-23 Pin Definition: 1. VCC 2. Output 3. GND 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 Features ● ● ● ● ● Ordering Information o 100% tested at 125 C Temperature compensation function Chopper stabilized amplifier stage. Optimized for BLDC motor applications. Reliable and low shifting on high Temp condition.
