no 3v and 5v section voltage reading

[kalilinux25]

Hi my board is HUSK MB 11309-248.4TU05.021

The board is plugg and consuming 13 milliamp
measuring the 3v coil no reading and the 5v coil no reading


Ive measure the pins in PU4103 ( RT8223M)
1- NO READING
2- NO READING
3- 4.4V
4-NO READING
5- NO RADING
6- NO RADING
7-3.3V
8- 5V
9-19V
10- NO RADING
11-3.3V
12- 3V

16-4.4V
17-3.3V
18- NO READ
19-5V
20- NO READING
21-2V
22-2V
23-NO READING
24- 5V

i really need how to identify if the PU4103 is faulty or not

Double check your pin numbering, it doesn't match with the datasheet.

ALL BLANK ARE NO READINGS

SORRY I didnt notice

Re: no 3v and 5v section voltage reading

Your readings are still wong as you have not counted pins correctly. PIN8 is VREG3-so should be 3.3V and PIN17 is VREG5-so should be 5V. You mentioned pin8 at 5V and pin17 at 3.3V which is impossible if you counted pins correctly. Look for the dot mark on your IC. Thats pin1. Look for datasheet and try to understand how pins are counted.@Kalilinux25, i dont want to be harsh but you have 289 posts to your credit and you still dont know how to count pins correctly-That's not a good sign. You need to invest in basic knowledge first.

ive reply for the new reading sir

Re: no 3v and 5v section voltage reading

I dont know how you take readings but i'm surprised by your readings:

01. PIN15-its GND. You mention its 3.3V
02.PIN1-Entrip1-Voltage should be 1.0-1.5V approx. Impossible to have 5V there. Same for pin6 as ENTRIP2.

Infact i didnt read carefully all your pin readings as it doesnt make any sense.

Re: no 3v and 5v section voltage reading



Ive read again the pin 1 it is 5v reading

Re: no 3v and 5v section voltage reading

Leave ENTRIP1 floating or drive it above 4.5V to shut down channel 1.
