A3141, A3142, A3143, A3144

Sensitive Hall-Effect Switches, High-Temperature

The A3141, A3142, A3143, and A3144 have been phased out of production as of October 31, 2005, and has been replaced by the A1101, A1102, A1103, and A1104 next-generation continuous-time unipolar switches.

For samples and information on the replacement part, please refer to the A110x family.

Description

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points.

Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse-battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small- signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The A3141- and A3142- are improved replacements for the UGN/UGS3140-; the A3144- is the improved replacement for the UGN/UGS3120-.
