Other Parts Discussed in Thread: TCAN4550-Q1
Masters,
We are promoting TPS65381A-Q1 to replace NXP FS6500/FS6400. And customer has some requirements for the wake up function. Since FS6500 has CAN interface wake up and multiple GPIOs wake up, and TPS65381A also have a CAN wake up PIN, but from the datasheet, I can see that the CAN_WU pin is only a voltage sensitive pin and have no difference with general GPIO wake up function, how can we realize CAN interface wake up? Another question is, the customer requires 3 GPIOs for wake up the PMIC, but TPS65381A-Q1 only have one wake up GPIO, do we have some recommendations to realize multiple GPIO wake up? Adding OR Gate is a choice, but the current will be a problem.
Do we have more powerful SBC to replace FS6500/6400?
Thanks and looking forward to your feedback.
Best Regard
Eric Fu
