LV8282PV屬于集成電路（IC）的電機(jī)驅(qū)動(dòng)器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的LV8282PV電機(jī)驅(qū)動(dòng)器，控制器產(chǎn)品屬于電機(jī)驅(qū)動(dòng)器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實(shí)現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)載和預(yù)期應(yīng)用的特性有很大差異，范圍從用于有刷電機(jī)的簡(jiǎn)單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級(jí)閉環(huán)運(yùn)動(dòng)控制。

Overview

LV8282PV is a system driver IC which incorporates driver circuits

for CD/DVD player system on a single chip with 4 BTL type channels.

It adopts 4 output and 5 control input method to use 4ch BTL for

SLED and LOADING. When switched to LOADING mode, you can

select a control reference voltage between IC internal voltage mode

and external voltage (VREF input) mode. During LOADING

operation, even if control reference voltage is not supplied, you can

still operate the IC without any need for another supply voltage.

LV8282PV incorporates a pin to switch the operation of variable

REG circuit independently. Therefore, this IC is suitable to use as

regulator.

The dynamic range of this IC is wide with linear MOS technology.
