AM5680M28-E1

Data Sheet 5-CHANNEL MOTOR DRIVER FOR DVD PLAYER General Description The AM5680 is a five-channel BTL driver IC for driving motors and actuators used in DVD player. It contains two independent precise voltage regulators with adjustable range from 1.5V to 4V. Furthermore, an under voltage detector is provided for system reset. The AM5680 is available in standard HSOP-28 package.
