CMD4510
Motor Driver for Portable DVD Player with DC-DC Step Down Converter
DESCRIPITION
Outline Drawing
The CMD4510 is a 4-channel BTL driver IC for
driving the motors and actuators such as used in DVD
player and consists of two DC-DC Step Down
Converters. It is pretty fit for portable DVD player
application. Package material is Pb Free for
environmental protection.
FEATURE
z 4-channel BTL:
1) Two channels are voltage-type BTL
drivers for actuators of tracking and focus. Two
channels are voltage-type BTL driver for sled
and spindle motors. It is also built-in two DC-DC
converters.
2) Wide dynamic range for motor drive
[3.6V (typ.) when Vcc= 5V, at RL= 20Ω¸ load].
z 2 DC-DC Step down converters:
1) Efficiency up to 85%
2) Operation from 4.5~16V
3) Typical frequency operation to 240KHz.
4) Over voltage protection built-in.
5) Over current protection built-in.
z Common circuit
1) Level shift circuit built-in.
2) Thermal shut down circuit built-in.
3) Mute mode built-in for motor drive. EN1, EN2 mode control for two set of DC-DC
step down converters.
APPLICATIONS
● BTL driver for portable DVD player with DC-DC power management
