AN8387S Datasheet, PDF (1/6 Pages) Panasonic Semiconductor – 2-channel Linear Driver

ICs for CD/CD-ROM Player
AN8387S
2-channel Linear Driver
s Overview
The AN8387S is an IC which incorporates 2 circuits of
BTL drivers for driving various DC motors such as actua-
tors (focus, tracking traverse), spindles, and loading of
the CD players.
s Features
• Operating supply voltage range ; V_CC=3.5V to 9V
PV_CC=1.5V to 9V
• Built-in 2 circuits of voltage driven BTL drivers
(maximun drive current : 500mA)
• Quiescent current (current consumption at no input) ;
3.2mA
• Provided with power control pin
• Provided with driver output voltage limiting pin
• Built-in thermal protective circuit
(operating temperature : 160°C typ.)
s Applications
Linear driving of the DC motors and actuators of the
CD players. CD radio cassette tape recorders, and so
on.
