Capacitor and resistor values

Hi everyone,

I recently bought a used (broken) Nintendo switch console. To repair it I took it apart and took the motherboard out of the case. I then saw that someone obviously already tampered with the device, the power management IC (M92T36) is missing. That alone would’t be a great problem, you can get those for a couple of bucks from china.
The problem is that two more components are missing. If the USB-port is south (facing towards you), the horizontal capacitor in the direct north of the IC and one of the two resistors (the left of the two) to it’s right side are missing.
I’ve tried to photograph it, didn’t turn out too well, but I think you can get a rough idea about the parts I’m referring to.

Figuring the form factor out is not much of a problem, but I have absolutely no clue about the capacitance and resistance of the parts that are missing, I can’t simply measure them. Does anyone know the values or would be kind enough to measure them for me?

Thanks in advance for the help!

I’ll take some measurements from a working donor and let you know :slight_smile:

Hey there,

your last post with the component diagrams already tremendously helped, thank you so much!
Looking at the datasheet of ROHM’s BM92T30 (now I know it’s from ROHM it makes things a lot easier), which I think is a close relative to the M92T36 used in the switch, the resistors should both be 100 kOhms. Both these resistors should be more or less measurable while still on the board, there shouldn’t be much need to desolder them, if I correctly understood the datasheet. Inside is only a protection diode and heaps of MOSFETs in parallel to the resistors (Figure on top of page 23 of the Datasheet, Pins 31 and 32), so they shouldn’t have much of an influence on the value…
The capacitor is connected to Pin 36 (VCONN_IN) of the IC and should just be a stabilising cap for the chip’s supply, I’d guess something like 100 nF ceramic cap.
It would still be really helpful if you could confirm (or deny) my guesses.

Hey mate, I have just taken measurements.
Cap seems to read 0.8uF, and the two resistors are both the same value of 147k ohms.


Hey Ben,

Thank you so much for your support. I ordered parts, I hope I get them before the weekend, we’ll see. I will report if the parts worked or not!

Hey there,
just a short followup: I replaced the resistors with 100k resistors and the capacitor with a 1uF mlcc cap and it works like a charm! Thank you for the help @KiloooNL ! :smiley:
