Re: Toshiba L650 power problem
What voltages are you seeing now? Its hard for me to know what is wrong, so many possible reasons.
This is the description of pin 14 from the data sheet.
"Power-Source n-Channel MOSFET Switch Driver Output. When the adapter is not present or an overvoltage event is detected at the input, the PDSL output is pulled to GND with a 2.5kI (typ) resistor. Otherwise, it is typically 8V above the adapter voltage when the part is not using the battery. This is powered by an internal charge pump"
So the Gates of Q6002 and Q6005 should be about 19 + 8 = 27v above ground when they are supposed to be on.
