Hello,
We are encountering a weird behavior with the TPS259531.
This is the used schematic:
The initial conditions are:
- EN = ‘0’
- CHG_DET = ‘0’
- VBUS = 0V
When VBUS is raised to 5V and CHG_DET raised to 3.3V the voltage at OUT (Vp) jumps to the expected 1.5V (voltage divider). EN stays at 0V. For some reason the Voltage goes down to 1.05V after 25s, as you can see in the image below. This would indicate a leakage into OUT. Is this normal behavior? Do you see other probable sources for this?
thank you and best regards,
Ambroise
