  • Product introduction

The A3290 and A3291 Hall-effect latches are extremely temperature-stable and stress-resistantsensor, especially suitable for operation over extended temperature ranges (up to 125°C). Good high temperature performance is achieved through dynamic offset cancellation, reducing the residual offset voltage typically caused by overmolding of the device package, temperature dependence, and thermal stress. Both devices are identical except for the magnetic switchpoints. Both devices are not intended for use in automotive applications.

Both devices include the following components on a single silicon chip: voltage regulator, Hall generator, small signal amplifier, chopper-stabilized feature, Schmitt trigger, and open-collector output with short-circuit protection that draws up to 25 mA. To turn on the output, a strong enough south polarity magnetic field must be provided. To turn off the output, a North Pole magnetic field of sufficient strength must be provided. The board regulator allows operation with supply voltages from 3 to 24 V.

Both package types provide magnetically optimized packages for most applications. The LH type package is a SOT23W miniature low profile surface mount package, while the UA type package is a three-pin ultra-small SIP for via mounting. Both packages are lead (Pb) free and feature 100% matte tin leadframe plating.
