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…
Hello Yihe,
Okay and please correct other post reply since it is incorrect. Thanks!

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…
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…

Hi, Tom,
Compare the two .csv files: the "*jab.csv" only contains BlockWrite at 0xE2 (to set up the address) but does not contain BlockWrite at 0xE3 (to write the data), as shown in "*yen.csv" file => Importing data using "*jab.csv" file do NOT…
Part Number: UCD90320 Hi team,
Would you help to share how I can control below I2C expanded IO, want to output value. I didn’t find related register address, could you please check the project on your hand?
Thanks for your kindly support.

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…
