Part Number: UCD90320 We are observing an issue with UCD90320 device detection. The device is not detected during normal initialization/power-up. However, if the UCD_RST signal is forcefully asserted, the device comes up correctly and becomes fully functional…
Part Number: UCD90320 Other Parts Discussed in Thread: UCD90160A ,
Hi TI Team,
We have been using the UCD90160A across multiple designs and have leveraged its resequencing functionality extensively.
For our latest design, we selected the UCD90320…
Part Number: UCD90320 Hi, In UCD90320, we are trying to read register (B5h)BLACK_BOX_FAULT_INFO(USER_DATA_05) through PMBUS command which we are successfully able to read and analyze. In the datasheet it mentions we can clear the same by writing 0x00…
Part Number: UCD90320 Hi team, I have few queries regarding checksum computation in ucd90320 for remote upgrade of the device. Is the checksum calculated solely based on the configuration data? If the same configuration is exported as .txt file from the…
Part Number: UCD90320 Hi team
We are using UCD90320 in one of our projects and would like clarification on the behaviour of the 'Faults shutdown other rails' feature provided in the Fusion Digital Designer tool.
In our design, output of one EN pin…
Part Number: UCD90320
Hello TI Team,
We are using a UCD90320 on our board and have encountered an issue where the device no longer accepts new configuration files.
Issue Summary
Our board originally had configuration v1.
We then programmed…
Part Number: UCD90320 Hi Team
In our design, the output rail of a regulator is connected to AMON pin of UCD90320. Also, fault pin of the regulator is connected as GPI to one of the DMON pins. Expectation is that when fault goes low, UCD should capture…
Part Number: UCD90320 Hi, We are trying to remote upgrade the UCD90320 firmware through PMBUS script exported from the Fusion Digital Tool. The observations are as follows,The programming get's completed without any issue and the new firmware comes into…
Part Number: UCD90320 Tool/software:
Hi Sir,
I would like to configure the power-off sequence such that EN_RTVDD_0P77_MAC0 is turned off once AC_OK is pulled low.
However, based on waveform measurements, it appears that this setting is not functioning…
Part Number: UCD90320 Hi TI team,
We are using the UCD90320 in our design. For initial bring-up and validation, we programmed the device using the Fusion Digital Power Designer GUI (Version 7.10.1), and it worked as expected.
For our pilot build,…
