S30454CH BTL Motor Drive IC
Description
The S3045 is a four-channels BTL motor driver for driving the
actuators and motors for products of DVD-P/R/RW.
It embrace a two channels of current feed-back BTL drivers.
those use current feed-back process to minimize the current phase
shift from the load inductance of actuators
It supports various applications with pb free and heat-sink package.

◈ DVD-ROM
◈ DVD-RW
Features and Benefits
◈ 2 Channel are current feedback motor driver for actuators
◈ 2 Channels are voltage-type BTL drivers for sled and
loading motors.
◈ Separating power of SVcc and PVcc1,PVcc2 are to improve
power efficiency.

① Device Code
② Year & Week Code
◈ Dual Actuator drivers [ Current Feedback ]
The current feedback technique can reduce the current
phase shift caused By the load inductance of actuators
◈ Sled motor driver
A general OP-AMP connected to the input terminal helps
compute additions of differential inputs or signals.
◈ Loading motor driver
Single input linear BTL driver. The output structure are two
power OP-AMPS in bridge configuration.

Application Information
1. Thermal Shut Down Circuit
Actuators, Sled and
Loading motor
IHys
Bandgap Voltage
[ 1.25V ]
R2
R3 R1
R4
The built-in thermal shutdown circuit mutes turn off the output current when the chip temperature
reaches 175℃ (typ.). The hysteresis is set to 25℃ (typ.) by IHys,
so the circuit will start up again when the chip temperature falling down to 150℃ (typ.)
2. Reference Input & Stand-by Function
•Reference input [ BIAS PIN : PIN 27 ]
The applied voltage at the reference input pin must be between 0.8V and 6.5V
( when SVcc=8.5V )
•Standby input [ PIN28 ]
The following input conditions must be satisfied for the standby function
Stand-by input voltage
Below 0.5V [ or Open ]
Above 2.0V
OPERATION
The stand-by function is activated so the bias block and power
block are disabled
Recover the normal operation
