Tool/software:
Hi TI team,
I’m working with the DS90UB935 and DS90UB953 serializers and would like to clarify the output current capability of GPIO0~3.
Specifically, I’m planning to use one of the GPIOs to control a reset pin of an image sensor, which has an internal pull-up resistor with 1.8V. To avoid unintended behavior during power-up, I intend to add an external pull-down resistor to ensure the reset signal stays low until the GPIO is initialized.
Before finalizing the resistor value, I’d like to confirm:
What is the maximum output current capability (IOH/IOL) of GPIO0~3 when configured as outputs?
Is there a recommended maximum current load to ensure reliable logic levels and avoid stressing the GPIO drivers?
Any guidance or reference to datasheet sections or application notes would be greatly appreciated.
Thanks in advance!
