Power Management IC¶

The Pi 4 Model B uses two different PMICs depending on the board revision:

PMIC	Revisions	Manufacturer
MxL7704	Rev 1.1–1.4	MaxLinear
DA9090	Rev 1.5	Dialog / Renesas

The two chips are not pin-compatible and have different pad layouts. If replacing a PMIC, you must match the correct chip to the board revision.
