The A1242 Hall effect latch is a two-wire latch especially suited for operation
over extended temperature ranges, from –40 to +150°C. Superior high-tempera-
ture performance is made possible through the Allegro
patented dynamic offset
cancellation technique, which reduces the residual offset voltage normally caused
by device overmolding, temperature dependencies, and thermal stress.
The current-switching output technique allows for the reduction in cost in the
wiring harness because only two connections to the sensor are required. The cur-
rent-switching output structure also inherently provides more immunity against
EMC/ESD transients. These sensors have low magnetic thresholds, thereby
enabling more flexibility in the magnetic circuit design.
The Hall effect latch will be in the high output current state in the presence of a
magnetic South Pole field of sufficient magnitude and will remain in this state
until a sufficient North Pole field is present.
The A1242 includes the following on a single silicon chip: a voltage regulator,
Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trig-
ger, and a current source output. Advanced BiCMOS wafer fabrication process-
ing takes advantage of low-voltage requirements, component matching, very low
input-offset errors and small component geometries.
Suffix ‘L-’ devices are rated for operation over a temperature range of –40°C
to +150°C; suffix ‘E-’ devices are rated for operation over a temperature range
of –40°C to +85°C. Two A1242 package styles provide magnetically optimized
solutions for most applications. Package LH is a SOT23W, a miniature low-pro-
file surface-mount package, while package UA is a three-lead ultra-mini SIP for
through-hole mounting. Each package is available lead (Pb) free, with 100% matte
tin plated leadframes.
