ICs for Compact Disc/CD-ROM Player 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. 18.4±0.2 (5.15) (4.8) 28 22 21 15 (1.315) Unit: mm 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 external PNP-tr. Driver I/O gain setting is possible with an additional external resistor Since the output and input lines are separated and respectively collected together, pattern designing is relatively easy. 8.3±0.2 10.93±0.30 0.30–0.05 +0.10 0° to 10° 1 7 8 14 0.65±0.20 2.7±0.2 (1.2) 0.8 (6.4) 0.35+0.10 –0.05 Seating plane HSOP042-P-0400 s Applications CD/CD-ROM drive DVD/DVD-ROM drive s Block Diagram PVCC1 PVCC2 9 VO1+ VO1− VO2+ VO2− VO3+ VO3− VO4+ VO4− 20 18 17 16 15 14 13 12 21 22 24 23 11 0.1±0.1 1 2 PVCC 1 2 PVCC 8 SVCC detector Direction detector Direction detector Direction detector Direction changeover Thermal protection circuit 7 SV CC 1 2 3.3 V reg.
