5ch System Motor Driver
BD8203EFV
General Description
BD8203EFV is a 5ch system motor driver for CD/DVD.
A linear BTL mode can be adopted for all 5ch to reduce
noise. It has a Built-in 5V regulator, a changeable
regulator, and a general-purpose operational amplifier.
Designed best for car audio systems.
Features
Linear BTL method is implemented for the actuator
driver and the DC motor driver to reduce noise.
Loading driver 1ch
Built-in regulator 2ch (1ch output changeable)
MUTE function and Standby function
Built-in general-purpose operational amplifier 1ch
Built-in internal operational amplifier for the voltage
detection between driver outputs and for VC
standard
Applications
Car Audio
