How to set STUSB4710 PDO profiles
Hi, I am designing a 25W power supply for the raspberry pi 5 for my battery powered project. The buck regulator I am using has a fixed 5V output and I want to use the STUSB4710 to offer 5V 5A to the Pi. How can I program the registers to do so via I2...
VNH5019A-E- How to understand the thermal resistance (RθJA) in VNH5019A-E datasheet
I need to calculate and estimate the required thermal resistance and temperature in operation for thermal design. When I read in Section 3.1 of datasheet, I do not see the Rja I can use directly, instead, it presents a chipset configuration with vari...
Resolved! Looking for datasheet on diode
From what I can read on this diode it is from ST for sure, and it says VU beside the logo, the next line is M R, and the last line is GP922. Any help would be appreciated.

Revision code on STUSB4500
We have a batch of chips labelled M27400 and another marked M37400. Does this marking indicate the version number of the chips? I'm seeing a difference in behavior between them (the M34700 are reporting PE states I haven't seen previously). Thanks,
