MH187  Hall-effect sensor is a temperature stable, stress-resistant latch. 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.
MH187 includes the following on a single silicon chip: voltage regulator, Hall voltage 
generator, small-signal amplifier, chopper stabilization, Schmitt trigger, ESD circuit protection,
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.
MH187 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 three package styles 
available provide magnetically optimized solutions for most applications. Package types SO is 
an SOT-23(1.1 mm nominal height),SQ is an QFN2020-3(0.5 mm nominal height), a miniature 
low-profile surface-mount package, while package UA is a three-lead ultra-mini SIP for 
through-hole mounting.
The UA package SO type and SQ type are Halogen Free package. All of them have been
verified by third party Lab.
