Panasonic AN8377N Datasheet
ICs for CD/CD-ROM Player
■ Overview
The AN8377N is an IC which incorporates 3 circuits of
BTL drivers for driving various DC motors such as actuators (focus, tracking, traverse), spindles, and loading of
the CD players, and the +5V low drop type power supply.
■ Features
•
Operating supply voltage range ; V
CC
=5.5V to 18V
•
Built-in 3 circuits of voltage BTL drivers
(maximum drive current : 500mA)
•
Stable circuit operation against supply voltage change
and temperature change due to the built-in stabilized
power supply
•
Built-in +5V low drop power supply (external PNP
power transistor)
•
Built-in reset circuit (reset voltage : 4.82V)
•
Built-in thermal protective circuit (operating tempera-
ture : 159 ; typ.)
•
Built-in power cut circuit (motor driver 1 only)
■ Applications
Linear driving of the DC motors and actuators of the
CD players, CD radio cassette tape recorder, and so on.
