AEC-Q100 grade and under-hood temperature profile
This grade places it in the under-hood and engine-bay tier — the 125°C ceiling covers the worst-case ambient inside an ECU mounted on the engine block or transmission housing, where standard commercial or even industrial-grade parts would drift out of regulation. The part integrates a single-cell Lithium Ion/Polymer battery charger with over-temperature fault protection, so it handles both the charging profile and the thermal shutdown without an external supervisor IC.
Package and thermal pad — layout checklist
Surface-mount assembly per the standard VQFN footprint; the 0.50 mm pitch peripheral pads fan out on a two-layer board with 0.20 mm trace widths. The cut-tape (CT) and tape-and-reel (TR) packaging options cover both prototype and production volumes.
