Introduction

MH188 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. MH188 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. MH188 is rated for operation between the ambient temperatures - 40°C and 85°C for the E temperature range, and - 40°C to 125°C for the K temperature range. The two package styles available provide magnetically optimized solutions for most applications. Package SO is an SOT- 23, a miniature low- profile surface- mount package, while package UA is a three- lead ultra mini SIP for through- hole mounting. Packages is Halogen Free standard and which have been verified by third party lab.
