MH 248 Hall-effect sensor is a temperature stable, stress-resistant , micro-power switch. 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.
The MH 248 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 omni-polar magnetic fields for operation.
The MH 248 is rated for operation between the ambient temperatures –40°C and + 85°C for the E
temperature range. The four package styles available provide magnetically optimized solutions for most
applications. Package types SO is an SOT-23(1.1 mm nominal height),ST is an Tsot-25(0.8 mm nominal
height),SU is an USON(0.5 mm nominal height) ,a miniature low-profile surface-mount package, while
package UA is a three-lead ultramini SIP for through-hole mounting.
The package type is in a lead (Pb)-free/ Green version was verified by third party Lab.
