Hi,
I am working on a project where I would like to use PCA9685 to drive
power-mosfets (BUK9K25-40E or similar with ~800pF input capacitance).
However from the PCA9685 datasheet I cannot extract consistent information on
how to use the device with external drivers:
This leads me to the design questions:

For example the 10mA source current limited by inside of IC.
You can test the drive waveform then decide to use the series resistor,if there is high over shoot on the waveform you can consider about 10Ω resistor in series.
