A1210-A1214 are Allegro's new generation of Hall effect latching switches, featuring fast power-on time and low-noise operation. The device is produced with BiCMOS technology and programmed after packaging to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress.
The Allegro A1210‑A1214 family are continuous‑time Hall‑effect latches that integrate a voltage regulator, Hall‑voltage generator, amplifier, Schmitt trigger, and NMOS output transistor on a single silicon chip. They operate from 3.8 V to 24 V and feature a +30 V absolute‑maximum voltage rating for automotive and industrial motor‑commutation applications.
The datasheet includes detailed electrical and magnetic characteristics, thermal data, package dimensions, and a product selection guide for both surface‑mount (Package LH) and through‑hole (Package UA) options. It also outlines operating behavior, hysteresis, and continuous‑time benefits.
