Overview
The AN8816SB is a 4ch. driver using the power opera-
tional amplifier method. It employs the surface mounting
type package superior in radiation characteristics.
s
Features
Wide output D-range is available regardless of refer-
ence voltage on the system
Setting of driver input/output gain enabled by external
resistance
2ch. independently controllable PC (Power Cut) feature
built-in
Thermal shut down circuit (with hysteresis) built-in
Proper heat of IC controllable by separating the output
supply and setting each independently for 2ch.
Construction of 5V supply enabled by external PNP Tr
Accessary operational amplifier built-in
Relatively easy pattern design by separating and con-
centrating the input line and output line
s
Application
Actuator for CD/CD-ROM, motor driver

Description for use
Driver Portion
Calculate the driver gain by using the following formula for setting.
G =

R
IN1
+100 (
)
The power supply for Ch.1 and 2 is supplied from Pin20 and the power supply for Ch.3 and 4 is supplied from Pin9
independently.
Output amplitude is increased by increasing the supply voltage. Set the power supply voltage as necessary. However, always set
Pin7 of V
CC
to the maximum electric potential.
Pin8 and 21 may require a capacitor for ripple removal.
As protection functions, V
CC
reset circuit,V
REF
detector and heat protection circuit are incorporated.
The V
CC
reset circuit operates at approx. 3V and is released at 3.2V, when the supply (Pin7) decreases. For the V
REF
detector, the
protection function works at approx. 1V (max. 2V).
Also, the set temperature for operation of the heat protection circuit is approx. 180C .
PC (Power Cut) functions which can be independently controlled are incorporated in Ch.1 and 2.
5V Supply
By adding an external PNP transistor, 5V regulator can be constructed. Attach an external capacitor for loop filter to output Pin2.
In Pin1, the base current limiting circuit (typ. 10mA) is incorporated.
When the V supply is used, the external PNP Tr emitter must be connected to pin than Pin7 (SV
CC
pin)
OP Amp.
When the operational amplifier is not used, make connection as follows ;

Cautions for use
When the AN8816SB is used, take into account the following cautions and follow the power dissipation characteristic curve.
(1) Load current, I
P1
flowing in loads R
L1
and R
L2
is supplied through Pin20.
(2) Load current, I
P2
flowing in loads R
L3
and R
L4
is supplied through Pin9.
(3) Dissipation increase (DP
d
) inside the IC (power output stage) caused by loads R
L1
, R
L2
, R
L3
, R
L4
is as follow.
(4) Dissipation increase (DP
S
) inside the IC (signal block supplied from Pinu) caused by loads R
L1
, R
L2
, R
L3
, R
L4
is almost as
follows ;
(5) Dissipation increase during driver running is DP
d
+ DP
S
.
(6) Inside loss under no load (P
