AT5683 Datasheet | Aimtron Technology

Features ˙4 channel BTL motor driver. ˙Wide dynamic range.(4V(typ.) at Pre Vcc=8V, Pow Vcc=5V, RL=8Ω) ˙Separating Vcc into Pre and power (Power divides into CH1/2/4 and CH3), can make better power efficiency, by low supply voltage drive. ˙Mute operated indivisually CH4 and CH1/2/3. ˙All channels mute is stand by mode. ˙Suitable for low operation voltage DSP by wide D-range pre opamp. ˙Thermal shutdown circuit on chip. ˙patible with BA5983 Description The AT5683 is a 4-channel BTL driver IC for driving the motors in products such as CD/CDROM drives. Suitable for low operation voltage DSP by wide D-range pre opamp. Small surface mounting power package (HSOP28). Applications CD drives, CD-ROM drives, Block Diagram Aimtron reserves the right without notice to change this circuitry and specifications. 10F-1, 55, Tong-Kuan Road, Hsinchu, Taiwan, R.O.C.
