IC for CD Players
BA5817FM
Description
BA5817FM is a 5-channel motor driver. 4 channels are
BTL drivers and 1 channel is a reversible DC motor driver.
2 channels of BTL driver incorporate standard operational
amplifier in pre-driver. Output voltage can be set by
output voltage control pin in reversible DC motor driver.
Brake function is incorporated.
