A3161中文资料霍尔效应开关， 2线应用数据手册Allegro规格书

描述 Description

These parts are discontinued.  Samples are no longer available. For new customers or new applications, please refer to Allegro A1150 Series.

This Hall-effect switch is a monolithic integrated circuit designed to operate continuously over extended temperatures to +85°C. The unipolar switching characteristic makes this device ideal for use with a simple bar or rod magnet. The A3161ELT and A3161EUA are identical except for package.

Each device includes a voltage regulator for operation with supply voltages of 3.5 to 25 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and a constant-current open-collector output. Noise radiation is limited by control of the output current slew rate.
