A3213/4 Micropower Ultrasensitive Hall Effect Switches, Allegro Microsystems

The Allegro Microsystems A3213/4 ultra-sensitive, pole independent Hall-effect switches with a latched digital output are aimed at use in battery-operated, portable equipment. Their 2.4 V to 5.5 V operation and a unique clocking scheme reduces the average operating power use. The A3213 to 825 μW and the A3214 to 14 μW (typical, at 2.75 V).

Either a north or south pole turns on the output.

They include a Hall-voltage generator, small-signal amplifier, chopper stabilisation, a latch, and a MOSFET output.

AEC-Q100 automotive qualified
Micropower operation
Superior temperature stability
Low switchpoint drift
Insensitive to physical stress
High ESD protection

Description:
The Allegro Microsystems A1120, A1121, A1122, A1123, and A1125 Hall-effect, unipolar switches are temperature-stable and stress-resistant sensor ICs. High temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-molding, temperature dependencies, and thermal stress.They include a voltage regulator, Hall-voltage generator, ...
