A1120, A1121, and A1125  
Chopper Stabilized Precision Hall Effect Switches  
Features and Benefits  
Description  
Unipolar switchpoints  
The A1120, A1121, and A1125 Hall-effect, unipolar switches  
are extremely temperature-stable and stress-resistant sensor  
ICs, especially suited for operation over extended temperature  
ranges to 150°C. Superior high-temperature performance is  
made possible through dynamic offset cancellation, which  
reduces the residual offset voltage normally caused by device  
overmolding, temperature dependencies, and thermal stress.  
Resistant to physical stress  
Superior temperature stability  
Output short-circuit protection  
Operation from unregulated supply  
Reverse battery protection  
Solid-state reliability  
Small package sizes  
Eachdeviceincludesonasinglesiliconchipavoltageregulator,  
Hall-voltage generator, small-signal amplifier, chopper  
stabilization, Schmitt trigger, and a short-circuit protected  
open-drain output to sink up to 25 mA.  
An on-board regulator permits operation with supply voltages  
of 3 to 24 V. The advantage of operating down to 3 V is that  
the device can be used in 3 V applications or with additional  
external resistance in series with the supply pin for greater  
protection against high voltage transient events.  
Packages:  
For the A1120 and A1121, a south pole of sufficient strength  
turns the output on. Removal of the magnetic field turns the  
output off. The A1125 is complementary, in that for these  
devices, a south pole turns the A1125 output off, and removal  
of the magnetic field turns the output on.
