Hi Daniel,
I was able to look over and compare the devices, and I am not sure if the replacement would increase the current drive as they are very similar in their output capabilities. Are there any clues as to why the output current was limited to…
Hello Ari,
Unfortunately, we do not know if the UCC28180 can handle peaks of -2V as that has not been measured. We will have to go with the -0.3V limit in the datasheet.
However, please verify that the negative spikes are indeed present and not an…
Part Number: TPS51604 Tool/software: Dear TI support team,
We have big trouble in using the TPS51604. Sometimes the chip does not respond after a power cycle. We are experiencing a similar issue to what's described in the following threads:

Hi Zhang, We can see by the waveforms that the time constant of the SPI bus waveform of TPS92682 is too large and therefore you will need to reduce the resistor value of the pull up resistor at the MISO line (τ=RC) . MISO is an open drain and therefore…

Hi Stanislav Stilyanov , yes I did follow the sequencing diagram in section 6.12.2.2. Basically everything is powered by 1.8V aside from VDD_CORE and LPDDR. One thing that I see is incorrect in my design is that VDD_CANUART is connected to 1.8V with VDDSH_CANUART…
Part Number: AM62A7-Q1 Other Parts Discussed in Thread: AM62A7 Tool/software: Hi Team,
We have made a custom board of AM62A7 with reference EVM board schematic. Below are the steps we have followed for booting.
1) Power up the device and validated…
