Other Parts Discussed in Thread: TPS3702
Hi team
Here is the design I develop for monitoring the MCU VCC. I use TPS3702 to monitor the MCU VCC and shunt down the LMR14020 by connecting the OV pin to EN pin when the MCU VCC is too large.
1. so here I want you to help check the schematic.
2. Especially whether the Rpu(10k) is appropriate, because the Rpu used in the reference design of LMR14020 is usually hundreds of K. I don't know whether the Rpu(10k) I selected is appropriate, and how to find the maximum input current of the EN pin of LMR14020 from datasheet.
Best Regards
