A1180 – A1184  
Preliminary Data Sheet  
Two-Wire, Programmable, Chopper-Stabilized,  
Unipolar Hall-Effect Switch  
PRELIMINARY DATA SHEET  
SUBJECT TO CHANGE WITHOUT NOTICE  
The A118X is a two-wire, unipolar, Hall-effect switch family designed  
for use in high-temperature applications. This device uses a patented high  
frequency chopper-stabilization technique on Allegro's new DABIC5  
BiCMOS wafer fabrication process to achieve magnetic stability and to  
eliminate offset inherent in single-element devices and from harsh-  
application environments.  
The A118X FAMILY of devices incorporates a programmability  
function to allow for external trimming of the operate point.  
The  
programming is performed after final packaging of the sensor and  
placement of the Single In-Line Package (SIP) into the application. This  
advanced feature allows for optimization of sensor switching performance  
by effectively accounting for variations caused by magnet and SIP  
placement tolerances.  
These devices provide on-chip transient protection. A zener clamp on  
the power supply protects against over-voltage conditions on the supply  
line.  
The output of the A118X FAMILY, with the exception of the A1180/2,  
will switch HIGH in the presence of a sufficiently large south-pole magnetic  
field and will switch LOW with the removal of the field. The A1180/2 has  
the opposite polarity as the others, switching LOW in the presence of a  
sufficient magnetic field and HIGH with the removal of the field.  
Two package styles provide a magnetically optimized package for  
most applications. Suffix “LH” is a miniature low profile package for  
surface-mount applications; suffix “UA” is a three-lead ultra-mini Single  
Inline Package (SIP) for through-hole mounting.  
Factory programmed versions also available, see A1140/42/43/45.  
Programming software and/or hardware demonstration kits also available  
see ASEK-01 on the Allegro web site, www.allegromicro.com.  
See typical application drawing for UA pinning.
