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.
