AN8813NSB
4-channel driver IC for optical disk drive
s Overview
The AN8813NSB is a 4-channel driver IC of the
BTL method. Ch.1 is used only for the loading
motor with little gain dispersion.
s Features
• For the loading motor channel, there are 4 modes,
that is, forward rotation, reverse rotation, brake
and standby modes, and you can select a mode
among them. The gain of it is fixed to 6 dB (±0.5
dB) with a small dispersion among the products.
• 3.3 V supply voltage is available due to an exter-
nal PNP-tr.
• Driver I/O gain setting is possible with an addi-
tional external resistor
• Since the output and input lines are separated and
respectively collected together, pattern designing
is relatively easy.
s Applications
• CD/CD-ROM drive
• DVD/DVD-ROM drive
