TSH188Ultra High Sensitivity Hall Effect Latch 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 • Temperature compensation function • chopper stabilized amplifier stage. • Optimized for BLDC motor applications. • Reliable and low shifting on high Temp condition. Application • High temperature Fan motor • 3 phase BLDC motor application • Speed sensing, Position sensing, Current sensing • Revolution counting • Solid-State Switch • Linear/Angular Position Detection Ordering Information Part No. Note: “G” denote for Halogen Free Product Absolute Maximum Rating (Ta = 25oC unless otherwise noted) Note: Do not apply reverse voltage to Vcc and Vout Pin, It may be caused for Miss function or damaged device.
