A3250 and A3251

Field-Programmable, Chopper-Stabilized

Unipolar Hall-Effect Switches

The A3250 and A3251 are field-programmable, chopper-stabilized, unipolar Hall-

effect switches designed for use in high-temperature applications. These devices

use a chopper-stabilization technique to eliminate offset inherent in single-element

devices.

Package UA, 3-pin SIP

The A3250 and A3251 are externally programmable devices. The devices have a

wide range of programmability of the magnetic operate point (B_OP) while the hys-

teresis remains fixed. This advanced feature allows for optimization of the sensor

switchpoint and can drastically reduce the effects of variations found in a produc-

tion environment, such as magnet and device placement tolerances.

These devices provide on-chip transient protection. A Zener clamp on the power

supply protects against overvoltage conditions on the supply line. These devices

also include short-circuit protection on the output.

The output of the A3250 switches LOW when subjected to a south-polarity mag-

netic field with a flux density that exceeds the threshold for B_OP, and switches

HIGH when the field drops below the magnetic release point, B_RP. The output of

the A3251 has the opposite polarity, switching HIGH in a south-polarity magnetic

field that B_OP, and switching LOW when the field drops below B_RP

The other differences in the devices are the power-on state. The A3250 powers-on

in the HIGH state, while the A3251 powers-on in the LOW state.
