LV5682P集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

LV5682P屬于集成電路（IC）的特殊用途穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的LV5682P特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機管理等。

Overview

The LV5682P 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.
