Chip Check

How to read it

• The live chip is drawn as it sits on the board, top view - pin 1 at the dot. Each pin shows what it should read in the state you pick (off, standby, on, charging).
• Tap a pin and see how the chip behaves when that pin has no input. A missing boot cap, a shorted output or a pull-up that is not fitted. This helps a lot to understand the chip.
• The scope panel shows every pin over the last seconds, the way an oscilloscope would.
• Only the marking? Search the letters printed on top of the chip.
• Everyone can see what a chip does before paying for a part, and a technician can compare the readings with what each pin should have.

About the data

Every chip here is built only from the datasheet its manufacturer publishes for everyone on its own website: the pinout, the electrical tables, the example circuit and how its protections behave. Each chip card links to that datasheet, so you can check every value yourself. "Not given" means the datasheet doesn't state that value.

Need a chip that isn't here? Post its part number and a link to its datasheet on the maker's own website on the NoPowerFix forum. We check that it's the official, publicly available datasheet and add the chip - we keep adding chips this way.
