Resistant to Physical Stress
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 3.8 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. Three package styles provide a magneti-
cally optimized package for most applications. Suffix ‘–LT’ is a minia-
ture SOT-89/TO-243AA transistor package for surface-mount applica-
tions; suffix ‘–U’ is a three-lead plastic mini-SIP while suffix ‘–UA’ is a
three-lead ultra-mini-SIP.
