343S00282 Power Management IC for iPad mini 5 (2019)

The iPad mini 5 from 2019 packs a lot into a small body, and its main power management chip is a 400-pin BGA. When it fails, the mini usually won't boot, or it starts with display or touch faults that don't go away with a new screen.

This listing sells the Apple 343S00282 power management IC for the iPad mini 5 (A2133, A2124, A2126, A2125). The listing gives its pin count as 400. A smaller 182-pin chip, 343S00286-A0, is also listed for the mini 5.

When the main PMIC is a suspect

• No boot with a good battery and no short on the main line.

• Display or touch faults with known-good screen parts.

• Abnormal current at power-on.

• Liquid damage under or around the chip.

Working on a small board

The mini's board is compact, so nearby parts sit close to the PMIC. Shield them, use a preheater, and keep the hot air focused. Check the rails of the smaller power chip too, so you don't replace the wrong part.

After fitting, measure the rails and test boot, touch, Apple Pencil and charging before closing the mini.
