4.1 Equipment

To evaluate the functionality the DRSS feature on the BQ25773, the following equipment is required:

  1. TI EVM: BQ25773 evaluation module (EVM).
  2. EMI Analyzer/Signal cable: A Rhode & Schawarz ESRP3 or equivalent CISPR compliant EMI Test Receiver.
  3. EMC Test Chamber: Shielded room for electromagnetic compatibility (EMC) testing.
  4. LISN'S: Two line impedance stabilization networks (LISN's), one for each power line.
  5. Power Supply: DC power supply capablsu of supplying 20V at 5A.
  6. Load: Kepco BOP36-6M, DC 0 to ±36V, 0 to ±6A, or equivalent. When testing without a real battery, connect 2000uF of capacitance across the battery input.
  7. Computer: A computer with at least one USB port and a USB cable.
  8. Communication Kit EV2400 or equivalent communication adapter.
