Overview
A1126 Chopper-Stabilized Omnipolar Hall-Effect Switch Features and Benefits • AEC-Q100 automotive qualified • Omnipolar operation • Low switchpoint drift • Superior temperature stability • Insensitive to physical stress • Reverse-battery protection • Robust EMC capability • Robust ESD protection Packages: 3-pin SOT23-W 2 mm × 3 mm × 1 mm (suffix LH) 3-pin ultramini SIP 1.
5 mm × 4 mm × 3 mm (suffix UA) Not to scale Approximate footprint Description The A1126 integrated circuit is an omnipolar, ultrasensitive Hall-effect switch with a digital output.
This device has an integrated regulator permitting operation to 24 V.
This device is especially suited for operation through extended temperature ranges, up to 150°C.
Superior high-temperature performance is made possible through an Allegro™ patented dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
The A1126 Hall-effect switch inclu...
