About datasheets

A datasheet is the chip maker’s own document: pinout, typical application circuit, enable thresholds and protection behaviour. When a schematic is missing, the datasheet of the controller is often enough to check a power stage.

Search by the marking on the chip. Laptop power ICs are frequently marked with a short top code instead of the full part number, so try both.
