com CMD4510 Motor Driver for Portable DVD Player with DC-DC Step Down Converter DESCRIPITION 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.
Outline Drawing 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.
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.
