DRV401AQRGWRQ1-Automotive, Fluxgate Magnetic Sensor Signal Conditioning IC for Closed-Loop Applications

The DRV401-Q1 device is fully qualified for automotive applications and is suitable for motor control drive and battery monitoring systems.

When used with a magnetic sensor, the DRV401-Q1 monitors 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-Q1 device directly drives the compensation coil or connects to external power drivers. Therefore, the DRV401-Q1 combines with sensors to measure small to large currents.

To maintain the highest accuracy, the DRV401-Q1 demagnetizes (degausses) the sensor at power-up and on demand.
