BIPOLAR HALL-EFFECT SWITCH

FOR HIGH-TEMPERATURE OPERATION

This low-hysteresis bipolar Hall-effect switch is an extremely

temperature-stable and stress-resistant sensor especially suited for

operation over extended temperature ranges to +150°C. Superior

high-temperature performance is made possible through a novel Schmitt

trigger circuit that maintains operate and release point stability by

compensating for temperature changes in the Hall element. Additionally,

internal compensation provides magnetic switch points that become more

sensitive with temperature, hence offsetting the usual degradation of the

magnetic field with temperature. Its low hysteresis makes this device

ideal for detecting small changes in magnetic field strength or for use

with inexpensive magnets.

The device includes on a single silicon chip a voltage regulator,

quadratic Hall-voltage generator, temperature compensation circuit,

signal amplifier, Schmitt trigger, and a buffered open-collector output to

sink up to 25 mA. The on-board regulator permits operation with supply

voltages of 4.5 volts to 24 volts.

The first character of the part number suffix determines the device

operating temperature range. Suffix ‘E–’ is for -40°C to +85°C, and

suffix ‘L–’ is -40°C to +150°C. Two package styles provide a magneti-

cally optimized package for most applications. Suffix ‘–LT’ is a minia-

ture SOT89/TO-243AA transistor package for surface-mount applica-

tions while suffix ‘–UA’ is a three-lead ultra-mini-SIP.
