Other Parts Discussed in Thread: TPS2552
Hello.
TUSB2046I is driven by 3.35V.
TPS2552 is driven by 5V.
Is the connection of these devices correct in the figure below?
The OVRCUR-input is pulled-up by 3.3V because the FAULT-output of TPS2552 is open-drain.
The PWRON-output is not pulled-up because the PWRON-output is push-pull.
The conditions of the EN-input of the TPS2552 are described below
Page-6
"7.3 Recommended Operating Conditions"
VEN Enable voltage 0V to 6.5V
VIH High-level input voltage on EN MIN 1.1V
VIL Low-level input voltage on EN MAX 0.66V
