Other Parts Discussed in Thread: TDA4VM
Hello Expert,
Our customer is considering tps65941212 and tps65941213 for use with TDA4VM.
So I have some questions like below.
You can send it to me by e-mail. (michael.jeong@arrow.com)
1. What's the difference between tps65941212 and tps65941213?
As I know, there is NVM.
I'd like to know exact difference to support our customer.
2. What's the default setting in VNM for VCCA_PG_SET?
3. When I look at the register of the data sheet, it says “Default from NVM memory”, so it will be different from the reset default value.
Could you please deliver the NVM setting value?
4. The source power from Common Processor B’D to PMIC is all applied to VSYS_3V3.
When I look at the data sheet, I think that it is possible to supply power for PVIN_B = 5V, PVIN_LDO/VCCA/VIO_IN = 3.3V.
Can we use as I mentioned?
I have to attend meeting w/ our customer for design tomorrow.
I'm looking forward to receiving your feedback ASAP.
Best Regards,
Michael
