TPS2373: Vc_in floating

Part Number: TPS2373

Hi Team, 

based on before question below, 

TPS2373: about VCIN - Power management forum - Power management - TI E2E support forums

it mentioned Vc_in should be connected to a voltage to ensure proper operation, on my customer side, they have made board but Vc_in is floating, so just want to check if PD function can still works normally at such condition.  I know Vc_in will affect TPL/TPH/BT indicator, but except for this, can PD function of TPS2373 work normally? 




  • Hello Given, 

    Glad to see that other E2E posts are being searched!

    No we cannot guarantee normal operation without VCin connection to a voltage supply. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
