Two-Wire Chopper-Stabilized Hall Effect Latch

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.

Package LH, 3-pin Surface Mount

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.

Package UA, 3-pin SIP

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.
