343S00247 PMIC for iPad Pro 12.9 3rd Gen / iPad Pro 11 1st Gen (2018)

The 2018 iPad Pros share a number of board parts across the 11-inch and 12.9-inch models, and this 121-pin power management chip is one of them. Stocking it covers both sizes from that year.

This is the Apple 343S00247 power management IC for the iPad Pro 12.9-inch 3rd gen (A1876, A2014, A1895) and the iPad Pro 11-inch 1st gen (A1980, A2013, A1934). The listing gives its pin count as 121.

When to look at it

• No boot with the main PMIC's rails present.

• A rail supplied by this chip missing.

• A short traced to the chip.

• Damage from a bent chassis near the chip.

About 2018 iPad Pro boards

These iPads are thin and prone to bending, which can crack solder joints under BGA parts. Inspect the board for flex damage before replacing chips, and use a preheater to avoid warping it further.

Once fitted, measure the rails, then test boot, Face ID, touch and charging. If the chassis is bent, straighten or replace it so the joints aren't stressed again.
