But any P-channel with 30-higher volts and 17- higher amps range would work for you just that the pins ( D,S,G ) match.Last edited by tibd; 07-06-2015, 12:41 PM. -

Hi guys
I have a MacBook Pro A1990 that takes 4.9 Volts and .592 to .615 amps on one port. The other port on the left side power cycles with about the same amount of volts an amps but quickly power cycles. The same thing happens on the other side but opposite. So on the left side the bottom port stays on and on the right side it's the top one. I think it is a CD3215 chip but I am not sure how to test it or where to get one. I have checked for voltage at ppbus_g3h and it has 12.6 V which is also on fuses f7000 and f7001 I checked pp1v2_s3 and it has 1.2 V then... -
Customer came in with shorted USB C chips, replaced and the chips are now responding beautifully HOWEVER, I am only getting 5Volts .25 amps (sometimes .243 amps) I see that the T2 chip is turning on, but I am not seeing any voltage at the SSD rails for example,
PP5VG3S_EN is not present which would somewhat indicate a PMIC U7800 issue, but I checked the voltage on the PMIC and that is present and not shorted. I tested for PP5V_G3S and those rails are not present.
ISL9240HI is present, I am also getting 12.30 volts at PPBUS_G3H so no shorts there. Both CD3217 chips were successfully... -
Hello everyone
Got a motorbike PCB that had 3 burned diodes.
The smaller ones have the marking PJ78 GS1M
And one larger one PJ78 GEX
Can someone help me identify them so I can be able to replace with same or equivalent?

Apreciate !
Thank you... -
Hello,
I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.
Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,... -
Is there any replacement on this ic RT6575DGQW what is the equivalent please?
