343S00203 Power Management IC for iPad 6 (2018)

The iPad 6 from 2018 added Apple Pencil support to the entry-level iPad, and many are still in daily use. When one stops booting with a healthy battery, the 440-pin power management chip is a key part to test.

This listing sells the Apple 343S00203 power management IC for the iPad 6th gen (A1893, A1954). The listing gives its pin count as 440.

Faults it can explain

• No boot at all with a good battery.

• Display or touch faults that don't go away with a new screen.

• Abnormal current draw at power-on.

• A short on one of its rails.

What to expect

This is a large BGA. Expect underfill removal, a preheater, pad cleaning and either a pre-balled chip or reballing. Check the battery, charge port and connectors first, since those are faster and cheaper to fix.

After the swap, check the rails, then test boot, touch, Apple Pencil pairing and charging. When all of those work, the iPad 6 is ready to go again. If it came in after a fall, check the screen adhesive and the home button flex while it's open.
