AM5766 Motor Driver ICs 5-channel BTL Driver for DVD player AM5766 The AM5766 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 1.25V to 4 V. Further, a free comparator is provided for spindle motor back emf detection. It supports a variety of applications. Also, Pb free package is selectable (Please refer to Marking Identification). Applications BTL driv.

AM5766 Features

* 1) 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. 2) Wide dynamic range [9.0V (typ.) when Vcc1= Vcc2= 12V, at RL= 20Ω load]. 3)
