HALL-EFFECT LATCHES
FOR HIGH-TEMPERATURE OPERATION
These Hall-effect latches are extremely temperature-stable and stress-
resistant sensors 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 symmetry by compensating for temperature changes in the Hall ele-
ment. Additionally, internal compensation provides magnetic switch points
that become more sensitive with temperature, hence offsetting the usual
degradation of the magnetic field with temperature. The symmetry capability
makes these devices ideal for use in pulse-counting applications where duty
cycle is an important parameter. The four basic devices (3185, 3187, 3188,
and 3189) are identical except for magnetic switch points.
Each device includes on a single silicon chip a voltage regulator, qua-
dratic 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
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 for -40
°
C to +150
°
C. Three package styles provide a magnetically
optimized package for most applications. Suffix ‘–LT’ is a miniature SOT-
89/TO-243AA transistor package for surface-mount applications; suffix ‘–U’
is a three-lead plastic mini-SIP, while suffix ‘–UA’ is a three-lead ultra-mini-
SIP.
