AT5683
Preliminary Product information
4-channel BTL Motor Driver for CD/CD-ROM
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/CD-
ROM 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,
