DESCRIPTION/ORDERING INFORMATION

The DRV401 is designed to control and process signals from specific magnetic current sensors made by

VACUUMSCHMELZE GmbH & Co. KG (VAC). A variety of current ranges and mechanical configurations are

available. Combined with a VAC sensor, the DRV401 monitors both ac and dc currents to high accuracy.

Provided functions include: probe excitation, signal conditioning of the probe signal, signal loop amplifier, an

H-bridge driver for the compensation coil, and an analog signal output stage that provides an output voltage

proportional to the primary current. It offers overload and fault detection, as well as transient noise suppression.

The DRV401 can directly drive the compensation coil or connect to external power drivers. Therefore, the

DRV401 combines with sensors to measure small to very large currents.

To maintain the highest accuracy, the DRV401 can demagnetize (degauss) the sensor at power-up and on

demand.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
