I have a problem with my MAX232 chip and can't find the solution. The schematic of the chip is in the attachment. The chip is soldered on to a PCB.
I've checked all the connections, the supply voltage and the grounding. The supply voltage is a steady 5V signal and the ground pins of the caps and chip are correctly connected so I'm guessing that isn't the problem.
The strange thing that I found out is that the VS+ pin is 4,5V and the VS- pin is 0V instead of the 8.5V and -8.5V according to the datasheet.
How can this be possible or is the chip burned?
Thanks in advance.
