338S00227-A0 Power Management IC for MacBook Pro 13 Touch Bar A1706

The Late 2016 13-inch MacBook Pro with Touch Bar uses several Apple power management chips on its board. When one fails, the machine can stay dead or show missing rails that point back to the PMIC.

This listing sells the Apple 338S00227-A0 power management IC, a 96-pin BGA part, for the MacBook Pro 13-inch with Touch Bar A1706 from Late 2016. The listing doesn't give a board position or say which rails it handles on this model.

Reasons to replace it

• Missing rails traced to this PMIC, with inputs and enables present.

• A short on its supply that leads to the chip.

• Liquid damage under or around the chip.

Prepare carefully

Use your board view to find the chip by its 338S00227 marking and confirm what it powers. Replacing a 96-pin BGA PMIC needs a preheater, a controlled profile and good pad preparation.

After fitting, check the rails it supplies before attempting a full boot. When they're all present at the right voltages, the board can move on to normal testing.
