Other Parts Discussed in Thread: TPS65910
Hello,
What is the maximum leakage current on the VDDS_RTC pin prior to the processor receiving nRESPWRON? Hopefully this is AM335x generic.
Customer issue is that TPS65910 PMIC VRTC only supports 100 uA until it leave "NO SUPPLY" state. If VDDS_RTC leakage is greater than 100 uA during this period (prior to the power up sequence starting so before nRESPWRON is asserted), then the TPS65910 may become stuck in "NO SUPPLY" state because VRTC cannot reach 1.8V.
