TSH193CX RFG

TSH193 Taiwan Semiconductor Pull-up Resistor Integrated Hall Effect Latch DESCRIPTION FEATURES TSH193 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. TSH193 includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, Pull-up resistor output. Advanced DMOS wafer fabrication processing is used to take advantage of low-voltage requirements, component matching, very low inputoffset 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. ● Chopper stabilized amplifier stage. ● Optimized for BLDC motor applications. ● Reliable and low shifting on high Temp condition. ● Pull-up resistor integrated ● ESD Protection >4kV HBM ● Compliant to RoHS Directive 2011/65/EU and in ● Halogen-free according to IEC 61249-2-21 TO-92S accordance to WEEE 2002/96/EC definition APPLICATION ● High temperature fan motor ● 3 phase BLDC motor application ● Speed sensing, position sensing ● Revolution counting ● Solid-state switch ● Angular position detection ● Proximity detection SOT-23 Pin Definition: 1.
