Tool/software:
Hi TI expert,
1.The TPS25750D in my demo board can work in dead battery mode(VIN_3V3=0V before type-c plug), everything is OK; But when assemble battery pack, and VIN_3V3 exist before before type-c plug, TPS25750D cannot work anymore after type-c plug, Capture the VBUS/CC line/VIN_3V3 waveforms as attached, also attach the schematic and configuration image .JSON file.
2.About the Quiescent current measurement: 1) Disconnect type-c connector(VBUS=0V); 2)using DC power supply to supply power to VIN_3V3 & PP5V accordingly and serial DMM in power supply circuit; 3)record the measure result; the actual VIN_3V3 quiescent current is 2.46mA & PP5V quiescent current is 0.36mA, which is quite different compared with the values in datasheet.
I tried to find answer from TRM, there is a 70h sleep_config register to control PD's sleep behavior, currently i suspect the sleep_config register's bit1 is de-asserted in the config image generated by customized GUI, which cause PD always in normal working mode.
Could you please share your comments about my above 2x questions, appreciated!
