Chopper-Stabilized Precision Hall-Effect Switches

FEATURES AND BENEFITS

DESCRIPTION

▪ꢀ AEC-Q100ꢀautomotiveꢀqualified

▪ꢀ Unipolarꢀswitchpoints

The A1120, A1121, A1122, A1123, 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.

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.

Packages:

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.

3-pin SOT23W

For the A1120, A1121, A1122, and A1123, a south pole of

sufficientstrengthturnstheoutputon.Removalofthemagnetic

field turns the output off. The A1125 is complementary, in that

for these devices, a south pole turns theA1125 output off, and

removal of the magnetic field turns the output on.
