343S00328 Power Management IC for iPad Pro 12.9 4th Gen (2020)

The 2020 iPad Pro 12.9-inch carries three Apple power management chips in this store's range, and this 182-pin one is the middle size. If your diagnosis points to the chip marked 343S00328, this is the matching part.

It's listed for the iPad Pro 12.9-inch 4th gen (A2229, A2069, A2232), with a pin count of 182. The listing doesn't say which rails it supplies or where it sits on the board.

Signs it could be failing

• A rail that this chip supplies is missing.

• No boot while the main PMIC rails are present.

• A short traced to the chip.

• Joint damage after a bend.

Tips before you order

Read the marking on your chip carefully. 343S00326, 343S00327 and 343S00328 all fit this iPad but do different jobs, so the number has to match. Check the rails of each chip separately to confirm which one has failed.

Fit with a preheater and fresh flux, then test boot, cameras, Face ID and charging before closing the tablet. Passing all four is a good sign the fix will last.
