Allegro A1185 and A1186 Datasheet
Datasheet 14 pages · 370 KB · EN
The A1185 and A1186 are ultrasensitive, two-wire, unipolar Hall effect switches produced on Allegro MicroSystems' DABICS BiCMOS process. They utilize a patented high-frequency chopper-stabilization technique to achieve magnetic stability and eliminate offsets inherent in single-element devices.

Questions answered in these manuals
What is the primary function of the A1185 and A1186 devices?
They are ultrasensitive, two-wire, unipolar Hall effect switches used to sense seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position.
What is the benefit of using chopper stabilization in these switches?
Chopper stabilization eliminates offsets that are inherent in single-element devices exposed to harsh application environments.
What is the supply voltage range for the A1185 and A1186?
The devices operate from 3.5 V to 24 V supply voltage.
