A3290 and A3291  
Chopper Stabilized, Precision Hall Effect Latches for  
Consumer and Industrial Applications  
Features and Benefits  
Description  
Symmetrical switchpoints  
Resistant to physical stress  
Superior temperature stability  
Output short-circuit protection  
Operation from unregulated supply  
Reverse battery protection  
Solid-state reliability  
The A3290 and A3291 Hall effect latches are extremely  
temperature-stable and stress-resistant sensors, especially  
suited for operation over extended temperature ranges (up  
to 125°C). Superior high-temperature performance is made  
possible through Dynamic Offset Cancellation, which reduces  
the residual offset voltage normally caused by device package  
overmolding,temperaturedependencies,andthermalstress.The  
twodevicesareidenticalexceptfortheirmagneticswitchpoints.  
They are not intended for automotive applications.  
Small package size  
Bothdevicesinclude,onasinglesiliconchip,avoltageregulator,  
a Hall-voltage generator, a small-signal amplifier, chopper  
stabilization, a Schmitt trigger, and a short-circuit protected  
open-collector output to sink up to 25 mA. A south polarity  
magneticfieldofsufficientstrengthisrequiredtoturntheoutput  
on. A north polarity field of sufficient strength is necessary to  
turn the output off. An onboard regulator permits operation  
with supply voltages in the range of 4.2 to 24 volts.  
Packages: 3 pin SOT23W (suffix LH), and  
3 pin SIP (suffix UA)  
Twopackagestylesprovideamagneticallyoptimizedpackage  
for most applications. Type LH is a miniature SOT23W low-  
profile surface-mount package, and type UA is a three-pin  
ultramini SIP for through-hole mounting. Both packages are  
lead (Pb) free with 100% matte tin leadframe plating.
