Obtaining a good accuracy over three decades (mA to A, 1-100 A, and 100-1000A) is quite challenging due to large amounts of noise in the system. This design solves this problem by using a high-resolution analogue-to-digital converter (ADC) and high-accuracy current shunt monitors from TI.
Features include:
- Full-scale accuracy of:
- 0.02% full-scale range (FSR) for <20A and <0.05% FSR for 20A to 1500A at 25°C
- 0.1% FSR for <20A and 0.25% FSR for 20A to 1500A at 50°C
- Suitable for 50mA to 1500A range current measurement; configurable to varied current spans
- High-side sensing and low-side sensing
- Supports bi-directional current
- Bi-directional current measurement: -1500A to +1500A.
