DRV421 Overview
Key Specifications
Package: Module
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.
Key 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
- Magnetic Core Degaussing Feature
- Diagnostic Features: Overrange and Error Flags
