MH163 Hall-effect sensor is a temperature stable, stress-resistant sensor. Superiorhigh-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.
MH163 includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, Totem pole output, thermal shutdown and high ESD protection. The Totem pole output could save a pull-high resistance in application circuit, thus save the space and cost. This type output also has larger drive capability and faster response speed.
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.
MH163 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 ultramini SIP for through-hole mounting.
Packages is Halogen Free standard and which have been verified by third party lab.
