DRV421 - Integrated Magnetic Fluxgate Sensor

Description

The DRV421 is designed for magnetic closed-loop current sensing solutions, enabling isolated, precise dc- and ac-current measurements.

This device provides both, a proprietary integrated fluxgate sensor, and the required analog signal conditioning, thus minimizing component count and cost.

Features

  • 1 High-Precision Integrated Fluxgate Sensor.
  • Offset and Drift: ±8 µT max, ±5 nT/°C typ.
  • Extended Current Measurement Range.
  • H-Bridge Output Drive: ±250 mA typ at 5 V.
  • Precision Shunt Sense Amplifier.
  • Offset and Drift (max): ±75 µV, ±2 µV/°C.
  • Gain Error and Drift (max): ±0.3%, ±5 ppm/°C.
  • Precision Reference.
  • Accuracy and Drift (max): ±2%, ±50 ppm/°C.
  • Pin-Selectable Voltage: 2.5 V or 1.65 V.
  • Selectab.
