Overview
The LV5682P-E is a multi-power supply system IC that provides four regulator outputs and two high side switches as well as a number of protection functions including overcurrent protection and overheat protection. It is an optimal power supply IC for car audio and car entertainment systems and similar products. It is possible to use it like the bus track etc. in the vehicle whose voltage of the battery is 24V because there is a range of the power-supply voltage up to 32V.
