343S00314-A0 Power Management IC (Big) for iPad 7 (2019)

The iPad 7 from 2019 was the first entry-level iPad with the 10.2-inch screen and Smart Connector. Its main power management chip is a 400-pin BGA that handles most of the board's rails, so a failure here usually stops the iPad from booting.

This listing sells the Apple 343S00314-A0 power management IC, the big PMIC, for the iPad 7th gen (A2197, A2200, A2198). The listing gives its pin count as 400.

Signs pointing to the PMIC

• No boot with a known-good battery.

• Abnormal current draw at power-on.

• Display or touch faults that stay with a new screen.

• A rail short traced to the chip.

Before replacement

Rule out the charge port, battery and screen connectors. Then confirm missing PMIC outputs with good inputs. The job needs a preheater, careful underfill removal and clean pads before the new chip goes on.

After fitting, check the rails and test boot, touch, Touch ID and charging. A clean result means the iPad 7 can return to service. Fit new screen adhesive, since the display is glued in place.
