Why this charger exists for automotive USB
The LT8698SEV#PBF is a single-output, 5V/3A USB charger IC from Analog Devices, designed specifically for automotive USB ports where the input rail can swing from 6V to 42V — covering 12V and 24V systems with headroom for load-dump spikes. It includes cable drop compensation, which means the voltage at the USB connector stays at 5V even when the load pulls 3A through a meter of cable — a common failure point in retrofit USB ports that sag under load.
Input range and thermal budget
The 6V to 42V input range eliminates the need for a separate pre-regulator or transient suppressor on most automotive buses — the part handles the 36V load-dump clamp typical in 12V systems without external clamping. Without a proper thermal land, junction temperature will exceed the 125°C limit under continuous load in a 85°C ambient.
