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.
