Texas Instruments DRV401/DRV401-Q1 Sensor Signal Conditioning IC

Texas Instruments DRV401/DRV401-Q1 Magnetic Sensor Signal Conditioning IC 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/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. This device offers overload, fault detection, and transient noise suppression. The Texas Instruments DRV401/DRV401-Q1 directly drives the compensation coil or connects to external power drivers. Therefore, the DRV401/DRV401-Q1 combines with sensors to measure small to large currents. The DRV401-Q1 devices are AEC-Q100 qualified for automotive applications.
