Single chip driver IC for slim CD-ROM, DVD-ROM

BH6544KV

Description

The BH6544KV is a 4-channel PWM driver IC for

CD-ROM, and DVD-ROM. Three-phase PWM

driver for spindle driving and PWM driver for sled

motor and actuator are integrated into a single chip.

Consumption current at stand-by mode can be

reduced to 0µA due to stand-by function.

Features

1) ON resistance of output power MOS is low.

Spindle section: 0.5Ω(Typ.)

2) VQFP48C package enables a smaller set.

3) Built-in stand-by circuit

4) Current limit, hall bias, FG output and

reverse protection function are integrated

into a three-phase PWM driver.

5) Built-in a thermal shut down circuit

6) Built-in a charging-pump circuit
