Overview

The LV56801P 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, overvoltage protection and overheat protection. It is an optimal power supply IC for car audio and car entertainment systems and similar products.

ACC (accessory voltage detection output): 100mA maximum output current, 0.25V voltage difference between input and output.

? Overcurrent protection function

? Overvoltage protection function, typ 21V (excluding VDD 3.3V output)

? Overheat protection function, typ 175oC

? On-chip accessory voltage detection circuit

? P-channel LDMOS used for power output block

CAUTION)

The protection functions are provided in order to improve the ability of the ICs to withstand breakdown, and they are not intended to guarantee safety when used under conditions outside the safe operating area or rated operating conditions. Use of the ICs under any conditions exceeding the safe operating area or above the IOmax, and especially use in overcurrent protection areas or under conditions in which they are subject to thermal protection, may reduce their reliability and result in permanent breakdown.
