Apr. 2005 Rev. 1. 1
BCD Semiconductor Manufacturing Limited
General Description
The AM5665 is a 5-channel BTL driver IC, in which
two channels drive DC motor, two channels with cur-
rent feedback drive the coils, such as the focus and the
tracking actuator of DVD player, and the other one
channel drives the bi-direction DC motor for tray.
The AM5665 is available in standard HSOP-28 pack-
age.
