This IC is 1 chip driver IC for spindle motor and 5 channel actuators. All of the motor and actuator of optical disk drive system (CD-ROM etc.) can be drived by only this IC. This IC has a direct PWM control system for Spindle and Slide channels drive due to reducing IC power dissipation.

This IC has three voltage supply terminals (for Spindle, Slide,Focus/Tracking and Loading) , and three voltage supply can be set separately.

Further more this IC has short braking select function,FG amplifier, thermal shut down circuit, standby circuit, reverse rotation detect circuit.

[ELECTRICAL CHARACTERISTICS]

Common

using N-type board

using P-type board

This IC's package is POWER-SSOP, so improving the board on which the IC is mounted enables a large power dissipation without a heat sink.

For example, using an 1 layer glass epoxy resin board, the IC's power dissipation is 2.6W at least. And it comes to 3.6W by using an improved 2 layer board.

The information of the N, P type board

is shown in attached.

[THERMAL CHARACTERISTICS]

SYMBOL PARAMETER

TSD

*note3

This TSD function start temperature doesn't show the guaranteed max. temperature of the devices. The guranteed max. temperature is Tj max. which is shown in "9. ABSOLUTE MAXIMUM RATING". The TSD function is a thermal protection in case the temperature of the devices goes up above Tjmax because of wrong use.

And these TSD temperature are the target temperatures for circuit design, not the guranteed temperatures.

(The TSD function of all the devices is not checked by a test in high temperature.)
