Hello,
We are working on a project with TCA9539QPWRQ1 in it.
Kindly review the attached schematics and let me know the review comments.
Melbin,
If P04-P07 are configured as outputs, then this implementation should have no issues. This would keep these pins either low or high, reducing current consumption. If these are configured as inputs, then they should be tied to either GND or to V_3P3_PHPL to prevent high current consumption by the input stages of the device.
Best,
Danny
