Low Side: High Bandwidth Current Amp and Fault Detection for Solar Inverters Reference Design
Description
This reference design provides a solution for an accurate shunt-based current measurement on the low side with an integrated fault-detection feature. It consists of a current sense amplifier which supports current sensing for a high bandwidth. The fault detection feature allows detection of undercurrent and overcurrent faults. The design provides a performance comparison between shunt-based current sensing and current sensing using a hall sensor.
Features
- Shunt based low side current sensing system with negative common mode supportCompact system for current sensingHigh bandwidth current sensing of up to 400kHzBidirectional current sensing supportIntegrated undercurrent and overcurrent detection with less than 1µs response timeLess than 0.3% error in measurement for complete DC current range (-3A to 15A)
