LV8282PV
Bi-CMOS IC
CD/DVD-ROM/RW 4.5ch Driver
htt p://onse m i.c om
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.
Function
• Incorporated POWER AMP 4ch (BTL method 4ch)
• IO MAX: 1A
• Incorporated level shift circuit (BTL method, incorporated in the entire 4ch)
• When BTL circuit of the 4th ch is in LOADING mode, you can select a control reference voltage between internal
reference voltage mode and VREF (external voltage) mode.
• Incorporated variable regulator control circuit (which uses an external NPN-transistor. Voltage is set by an external
resistor.)
• Incorporated ON/OFF switch function controllable independently by variable regulator
• Internal 5V regulator output pin
• Incorporated thermal shutdown protection circuit (TSD) (thermal shutdown protection signal output pin included)
• Incorporated charge pump

6. Reduced-voltage protection function (LVS)
When the voltage of internal regulator (REG5) is monitored and if the voltage is 3.6V (TYP) or lower, BTL output
(VO1, 2, 3, 4+-) and the external regulator (REGO) are turned off. When REG5 is 4.15V (typ) or higher, control is
performed according to truth value table (p3).

7. TSD
When TSDO is used with pull-up resistor, during operation of thermal shutdown circuit, the voltage level is set to “L”.
In this case, VO1, 2, 3, 4+- output of CH1, 2, 3, 4 are turned off.
(REGO: external regulator control circuit is not turned off.)
