MH 187 Hall-effect sensor is a temperature stable, stress-resistant latch. Superior
high-temperature performance is made sible 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.
The MH 187 includes the following on a single silicon chip: voltage regulator, Hall
voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short
circuit protected 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.
The MH 187 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
ultramini SIP for through-hole mounting.
The UA package type and SO type is Green package, both of them were verified by third
party Lab.
