Other Parts Discussed in Thread: TDA4VM
Hi Team,
We have a design that uses TI's TDA4VM processor.
In TI's reference design, both TPS65941212RWERQ1 and TPS65941111RWERQ1 were used as PMICs.
When the ECU is powered on, the power rails of the two PMICs can be output normally, but after 100ms, the power supply of the main domain is completely shuted.
However, the power of the MCU domain can be output normally. TDA4VM seems to have entered MCU Only mode, I don’t know what caused it.
The following is the schematic diagram of the power supply part of TDA4VM, please help analyze the cause of the problem, thank you!
Thanks in advance
Best Regards
Conn XU
