2.1 Hardware Overview

AMC-AMP-200A-EVM AMC-AMP-200A-EVM Hardware LabelsFigure 2-1 AMC-AMP-200A-EVM Hardware Labels

The AMC-AMP-200A-EVM has many hardware features, allowing the user to access and assess the EVM from many points in the signal chain. The default configuration is one 250µΩ shunt listed as R20 to sense ±200A applications.

Note:

This EVM is an example high current-sensing design and further designs can be modified per system requirements. Considerations included in definition table.

1. Vishay WSBS8518 Busbar Shunt Resistor
2. Via StitchVia stitching provides aeration to dissipate heat further.
3. AMC3302 InputAMC3302 differential analog input.
4. AMC23C15 InputAMC23C15 analog input.
5. Low-Side Power SupplyLow-side power supply connectors: terminal block J6 or test point connections.
6. LEDLED on to indicate device powered.
7. AMC3302Isolated current-sensing amplifier with integrated DC/DC converter. If smaller footprint desired or if high-side supply is available in the application such as from a gate driver or additional transformer winding, consider the AMC1302 isolated current-sensing amplifier.
8. TLV9002Operational amplifier for differential to single-ended conversion.
9. AMC23C15
  • Isolated comparator with adjustable threshold for overcurrent detection; 280ns propagation delay (typical). If <3µs latency is not required, consider omitting isolated comparator.
  • Isolated Overcurrent Protection Circuit
10. AMC3302 OutputsAMC3302 differential and single-ended outputs.
11. AMC23C15 OutputsAMC23C15 analog outputs.
