A1140, A1141, A1142, and A1143  
Sensitive Two-Wire Chopper-Stabilized  
Unipolar Hall Effect Switches  
Features and Benefits  
▪ Chopper stabilization  
Description  
The A1140, A1141, A1142, and A1143 devices are sensitive,  
two-wire, unipolar, Hall effect switches that are factory-  
programmed at end-of-line to optimize magnetic switchpoint  
accuracy.Thesedevicesuseapatentedhighfrequencychopper-  
▫ Low switchpoint drift over operating  
temperature range  
▫ Low sensitivity to stress  
▪ Factory programmed at end-of-line for optimized  
switchpoints  
▪ On-chip protection  
stabilization technique, produced using the Allegro advanced  
BiCMOS wafer fabrication process, to achieve magnetic  
stability and to eliminate offset inherent in single-element  
devices exposed to harsh application environments.  
▫ Supply transient protection  
▫ Reverse-battery protection  
▫ On-board voltage regulator  
▫ 3.5 to 24 V operation  
Commonly found in a number of automotive applications,  
these switches are utilized to sense seat track position,  
seat belt buckle presence, hood/trunk latching, and shift  
selector position. Two-wire unipolar switches, such as the  
A1140/41/42/43 family, are particularly advantageous in  
price-sensitive applications because they require one less  
wire for operation than do switches with the more traditional  
open-collector output. Additionally, the system designer  
inherently gains diagnostics because there is always output  
current flowing, which should be in either of two narrow  
ranges. Any current level not within these ranges indicates a  
fault condition. The A1140/41/42/43 family of switches also  
Packages: 3 pin SOT23W (suffix LH), and  
3 pin SIP (suffix UA)
