Part Number: UCD90320 Hi Team,
Per the datasheet, the “U” suffix part is recommended for “Telecom and Networking” equipment. In addition, they reference SEU events

You can read it using READ_VOUT (0x8B) command. Note this command is page specific i.e. it gives voltage value of a given page. You can change the page number using PAGE(0x00) command. Page 0 corresponds to rail 1, page 1 to rail 1 and so on. Also the…
Part Number: UCD90320 Hello,
My customer has a question about UCD90320:
Does the rail number correlate to the Analog Input Channel?
i.e. AMON4 = Rail 4?
What if pin not used on UCD for AMON4, then what should this look like?
Thanks, Zack
Hello Yihe,
Okay and please correct other post reply since it is incorrect. Thanks!

Hi Yihe,
Thanks for this feedback. I'll set up another forum post for the INA190A1 as you've suggested. As requested, here is a trace of the 3.3VA pin. It's measured on one of the UCD90320's decoupling capacitors with a ground blade on the scope…

Part Number: UCD90320 Hello expert,
May I know if EN or GPIO can set to retry function? We would like to EN set to low when fault occurs, and then retry automatically when fault is clear with certain period? I checked the video for pin selected rail state…
Part Number: UCD90320 Dear Team,
If the UCD90320 is only used as a voltage monitor, that is, it only uses the ADC interface of AMON[24:1], it should also need to burn the software code, right? If the device has no code, it will affect the inability to…
