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.
MH182 includes the following on a single silicon chip: voltage regulator, Hall voltage
generator, small-signal amplifier, chopper stabilization, Schmitt trigger, open-drain output.
Advanced CMOS 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
latches on, and only switches off when a north polarity field of sufficient strength is present.
MH182 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 an
SOT-23, a miniature low-profile surface-mount package, while package UA is a three-lead
ultra mini SIP for through-hole mounting.
The package type is in a Halogen Free version was verified by third party Lab.
