Product Summary

The A1152 ia a Two Wire Hall-Effect Switch. The A1152 is produced on the Allegro advanced BiCMOS wafer fabrication process, which implements a patented high frequency, 4-phase, chopper-stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.

Parametrics

A1152 absolute maximum ratings: (1)Forward Supply Voltage VCC: 28 V; (2)Reverse Supply Voltage VRCC: –18 V; (3)Magnetic Flux Density B: Unlimited G; (4)Operating Ambient Temperature TA: –40 to 150 °C; (5)Maximum Junction Temperature TJ(max): 165 °C; (6)Storage Temperature Tstg: –65 to 170 °C.

Features

A1152 features: (1)High speed, 4-phase chopper stabilization; (2)Low switchpoint drift throughout temperature range; (3)Low sensitivity to thermal and mechanical stresses; (4)On-chip protection: Supply transient protection; Reverse battery protection; On-board voltage regulator; 3.0 to 24 V operation; (5)Solid-state reliability; (6)Robust EMC and ESD performance; (7)Industry leading ISO 7637-2 performance through use of proprietary, 40-V clamping structures.
