TPS6594-Q1: Tying Interrupts of Multiple PMICs

Elian Seda

Part Number: TPS6594-Q1
Other Parts Discussed in Thread: TDA4VM,

Trying to tie together the nINT from both the TPS65941213RWERQ1and TPS65941111RWERQ1, to then be inputted into wakeup GPIO pin on TDA4VM microprocessor. The image below shows the abstracted connections but KiCad is throwing an error. Do I ignore this error or do I need to change something?

Hi Elian,

nINT should be pulled up to VCCA, as stated in the TPS6594-Q1 datasheet, and the nINT rail should be connected to the Safety MCU GPIO. These are shown in the TPS6594-Q1 Digital Connections figure in Optimized TPS65941213-Q1 and TPS65941111-Q1 PMIC User Guide for J721E, PDN-0C (Rev. A).

If these are the connections you are intending to make, the schematic looks like it will not have issues from a PMIC perspective. I would suggest looking into the error to make sure the schematic is interpreted properly by KiCad.

Regards,
Megan
