MH183 Hall-effect sensor is a temperature stable, stress-resistant sensor. Superior hightemperature 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.
MH183 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.
MH183 is rated for operation between the ambient temperatures -40℃and 85℃ for the E
temperature range, and -40℃to 125℃ for the K temperature range. The two package styles
available provide magnetically optimized solutions for most applications. Package SO is a SOT23, 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.
