Product Summary

The Allegro A1102 Hall-effect switch is next generation replacement for the popular Allegro 312x and 314x lines of unipolar switches. The A1102 is produced with BiCMOS technology, consists of devices that feature fast power-on time and low-noise operation. Device programming of A1102 is performed after packaging, to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique Hall element geometries and lowoffset amplifiers help to minimize noise and to reduce the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.

Parametrics

A1102 absolute maximum ratings: (1)Supply Voltage: 30 V; (2)Reverse Supply Voltage: –30 V; (3)Output Off Voltage: 30 V; (4)Reverse Output Voltage: –0.5 V; (5)Output Current: 25 mA; (6)Magnetic Flux Density: Unlimited G; (7)Operating Ambient Temperature: Range E: –40 to 85 ℃, Range L: –40 to 150 ℃; (8)Maximum Junction Temperature: 165 ℃; (9)Storage Temperature: –65 to 170 ℃.

Features

A1102 features: (1)Continuous-time operation: Fast power-on time, Low noise; (2)Stable operation over full operating temperature range; (3)Reverse battery protection; (4)Solid-state reliability; (5)Factory-programmed at end-of-line for optimum performance; (6)Robust EMC performance; (7)High ESD rating; (8)Regulator stability without a bypass capacitor.
