Hi,
Please note that the pictures for the TIDesigns are only for illustration, the picture caption mentions that "Fully assembled board (shown above) developed for testing and performance validation only, not available for sale."
The expectation…
Hi Patrick, I would follow the instructions from 9.4.1. and not the ones in the layout. I will change the layout instructions to make it consistent with the rest of the datasheet. a) The voltage reference should be stable because the ESR is less than…
Yes, the VDD1 LDO controller of the TPS65381A-Q1 may be re-purposed and used as a voltage monitor for different regulator that is not integrated into the TPS65381A-Q1 if the VDD1 LDO controller isn't used in the application.
The VDD1_SENSE pin may…
Hi Erik,
There is a TI Design http://www.ti.com/tool/TIDA-00548 which includes both devices and is using a DCDC for the core supply instead of the standard VDD1 LDO controller with external FET while using the VDD1_SENSE from the TPS65381A-Q1 to monitor…

Hi Otake-san,
If the MCU IO pin cannot be put into a high impedance state then the bugger needs to be between the DIAG_OUT and the GPIO pin. Whether or not a low pass filter is needed depends on the specific MCU and the ADC of the MCU, or other ADC that…
