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.
Features
1) Space saving by power save terminal
2) High-efficient driving due to independent power supply
for Pre Vcc and Pow Tr (CH 2 and CH 1,3,4)
3) Wide dynamic range
4) Built-in thermal shutdown circuit
