DRV401

SBVS070A − JUNE 2006 − REVISED OCTOBER 2006

Sensor Signal Conditioning IC for

Closed-Loop Magnetic Current Sensor

F_DEATURES

DESCRIPTION

DESIGNED FOR SENSORS FROM

VACUUMSCHMELZE (VAC)

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.

SINGLE SUPPLY: 5V

POWER OUTPUT: H-Bridge

DESIGNED FOR DRIVING INDUCTIVE LOADS

EXCELLENT DC PRECISION

WIDE SYSTEM BANDWIDTH

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.

HIGH-RESOLUTION, LOW-TEMPERATURE

DRIFT

BUILT-IN DEGAUSS SYSTEM

EXTENSIVE FAULT DETECTION

EXTERNAL HIGH-POWER DRIVER OPTION

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.

A_DPPLICATIONS

GENERATOR/ALTERNATOR MONITORING

AND CONTROL

To maintain the highest accuracy, the DRV401 can

demagnetize (degauss) the sensor at power-up and on

demand.
