3.5.5 function introduction to
AM5888S
1. Description
The AM5888S is a five-channel BTL driver IC for driving the motors and actuators such as used in DVD
player and consists of two independent precision voltage regulators with adjustable range from 1.5V to 4 V. It
supports a variety of applications. Also, Pb free package is selectable (Please refer to Marking Identification).
2. Fetures
◆
Two channels are voltage-type BTL drivers for actuators of tracking and focus. Two channels are
voltage-type BTL driver for sled and spindle motors. It is also built-in one channel bi-direction DC motor driver
for tray.
◆
Wide dynamic range [9.0V (
typ.
) when Vcc1= Vcc2= 12V, at RL= 20¦
¸
load].
