Bulk current injection (BCI) compliant automotive rear light reference design


Design files


This reference design for TPS92611-Q1 is an automotive rear light EMC compliant design. This is a direct connection to battery application with multiple single channel device and the fault pins are connected together to realize one-fails-all-fail function. This reference design provides some recommendations to pass the bulk current injection (BCI) test based on ISO11452-4 test 200mA substitution method and HKMC ES96200 standard.

  • Pass bulk current injection (BCI) Test: – ISO11452-4 200mA standard – HKMC ES96200 standard
  • Support one-fails-all-fail function
  • Suit off-board driving application
