Features

˙4 channel BTL motor driver. ˙Wide dynamic range.(4V(typ.) at PreVcc=8V, PowVcc=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. ˙Compatible 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-ran.
