Hi,
On page 24 (8.3.6) of the datasheet, the following sentence can be read in relation to the wake pin:
"Pin requires a 10 nF capacitor to ground for improved transient immunity in
applications that route WAKE externally. "
I understand that the 10nF MLCC is not required if the line is only routed internally on the print and is therefore not exposed to any major interference.
Can the circuitry be implemented without hesitation as shown in the appendix?
We want to be able to wake up the TCAN4550 through the microcontroller. That is the reason for the MOSFET on the wake pin.
In the data sheet on page 1 there is also a 33k resistor in front of the wake pin, the purpose of which is not entirely clear to me.
To save space, I would like to leave it out if it does not cause any problems.
Thanks in advance!
Best regards, Alen
