Other Parts Discussed in Thread: TPS7A85A
Hi Guang,
I have started the schematic using this IC. I have a few questions regarding the Digital output pins:
1) Can I leave the Warning and TC pins open as I don’t plan to use them or do I need to tie them to ground or terminate with a different impedance?
2) What is the VPU voltage? Is it different than Vs?
3) What is the purpose of RDIV in Figure 20 of the datasheet?
4) I plan to connect LEDs to Critical and PV pins. Have other customers done that before? It should be ok to connect LEDs to these pins, right?
Thanks,
Noman
