343S00144-A0 Power Management IC for iPad 5 (2017)

The 2017 iPad 5 is a common sight in classrooms and family homes, and it tends to live a hard life. Say one arrives on the bench with no sign of life, a good battery and a clean charge port: at that point the power management chip on the board is one of the next things to check.

This listing sells the Apple 343S00144-A0 power management IC for the iPad 5th gen (A1822, A1823). The listing gives a pin count of 361. A second part, 343S00206, is listed for the same iPad with the same pin count, so match the number on your chip.

Signs pointing to the PMIC

• No boot with a charged, known-good battery.

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

• A short on a PMIC rail.

• Liquid damage around the chip.

Tips for the job

Rule out the battery connector, charge port and screen connectors first. The PMIC is a large BGA, so use a preheater under the board and a controlled profile on top.

After fitting, check the rails and test boot, touch and charging before sealing the screen. A working iPad 5 can go straight back to homework duty.
