EMC Compliant High Side Current Sensing Reference Design with Overvoltage Protection
Description
This reference design focuses on high-side current measurement using a family of TI's voltage output current shunt monitors. It can be used for measuring high-side current in industrial applications: where the common-mode dynamics can drop below ground. Overall the design helps designers build Electromagnetic Compatibility (EMC) compliant circuitry around current shunt monitor devices while achieving high-accuracy current monitoring solutions in presence of wide range of common-mode voltages from -14V to +80V.
Features
- Wide common mode input range: -14V to 80VOvervoltage protection: 45VEFT protection up to 1KV as per IEC61000-4-4>130dB CMRR for DC-10HzOverall accuracy better than 2%70 µV offset and 1.4% gain error
Applications
- AC charging (pile) station
- Central inverter
- Rapid shutdown
