Description
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-temperature 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 device are required. The current-switching output structure
also inherently provides more immunity against EMC/ESD
transients. Thesedeviceshavelowmagneticthresholds,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 trigger, and a current
sourceoutput. AdvancedBiCMOSwaferfabricationprocessing
