FOperation notes

(1)

Tray motor driver voltage setting (forward mode)

Note: Tray driver output voltage cannot be set higher than the maximum output voltage for the power supply. The example above applies only when setting

(2)

Muting

〈Thermal shutdown〉

The output current is muted when the chip temperature

exceeds 175

_C (typically).

〈Supply voltage drop muting〉

The internal circuits turn off when the supply voltage

drops below 4.3V (typically), and turn on again when it

rises above 4.5V (typically).

(3)

Muting occurs during thermal shutdown and when

the supply voltage drops. In either case, only the driver

is muted. The output pin voltage during muting is the in-

(4)

Be sure to connect the IC to a 0.1

µF bypass capaci-

tor to the power supply, at the base of the IC.

(5)

Connect the radiating fin to an external ground.
