That covers under-dash USB hubs, rear-seat charging ports, and telematics boxes — anywhere the ambient under the dash can hit 85°C and the junction climbs another 40°C above that. ## 700 µA supply current — the always-on budget The IC draws 700 µA from the battery rail when the USB port is idle. In a vehicle with four such ports always powered, that is 2.8 mA total quiescent draw — a number the module architect needs to factor into the sleep-current budget for key-off drain compliance. ## Package and footprint — 32-VQFN with wettable flank Supplied in a 32-VFQFN exposed-pad package (5 mm × 5 mm body, 0.50 mm pitch). The wettable-flank option (RHBR suffix) allows automated optical inspection of the solder joints after reflow — a requirement for automotive production lines that cannot rely on X-ray alone for QFN packages.
