Other Parts Discussed in Thread: DRV8873
Tool/software:
Hello again, last week I made some questions related to DRV8873 but finally move to DRV8243.
We want to use 6 o these chips in parallel with same configuration.
Control "Mode" will be selected from a 3x2 jumper selector.
Below schematic and layout
(*) only Q1 is represented, Q2 to Q6 are the same.
1- is it fine the "jumper selector" mode?
2- is it fine to connect SR, iTRIP, DIAG, DRVOFF to GND?
3- is it fine to tight together all SLEEP (input) pins to the same gpio?
4- is it fine to tight together all nFAULT (output) pins to the same gpio?
5- finally, could you give a feedback about the layout?
-front layer (red) --> ground, +batt, outputs and signals
- 1st inner layer (green) --> ground
- 2nd inner layer (orange) --> +batt
- bottom layer (blue) --> ground and +batt
