  1. 1. DRV401 SBVS070B − JUNE 2006 − REVISED MAY 2009 Sensor Signal Conditioning IC for Closed-Loop Magnetic Current SensorFEATURES DESCRIPTIOND DESIGNED FOR SENSORS FROM The DRV401 is designed to control and process signals VACUUMSCHMELZE (VAC) from specific magnetic current sensors made byD SINGLE SUPPLY: 5V Vacuumschmelze GmbH & Co. KG (VAC). A variety ofD POWER OUTPUT: H-Bridge current ranges and mechanical configurations areD DESIGNED FOR DRIVING INDUCTIVE LOADS available. Combined with a VAC sensor, the DRV401 monitors both ac and dc currents to high accuracy.D EXCELLENT DC PRECISIOND WIDE SYSTEM BANDWIDTH Provided functions include: probe excitation, signal conditioning of the probe signal, signal loop amplifier, anD HIGH-RESOLUTION, LOW-TEMPERATURE H-bridge driver for the compensation coil, and an analog DRIFT signal output stage that provides an output voltageD BUILT-IN DEGAUSS SYSTEM proportional to the primary current. It offers overload andD EXTENSIVE FAULT DETECTION fault detection, as well as transient noise suppression.D EXTERNAL HIGH-POWER DRIVER OPTION The DRV401 can directly drive the compensation coil, or connect to external power drivers. Therefore, the DRV401APPLICATIONS combines with sensors to measure small to very large currents.D GENERATOR/ALTERNATOR MONITORING AND CONTROL To maintain the highest accuracy, the DRV401 canD FREQUENCY AND VOLTAGE INVERTERS demagnetize (degauss) the sensor at power-up and on demand.D MOTOR DRIVE CONTROLLERSD SYSTEM POWER CONSUMPTIOND PHOTOVOLTAIC SYSTEMS Patents Pending.
