DESCRIPTION
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.
