TECHNICAL NOTE
Motor Driver IC Series for Tape Record System
3 in 1 Motor Driver
for Digital Video Camera
BD6637KV/KS, BD6300KU
Description
The low power consumption, 3 in 1 motor driver, utilizes a DMOS linear output driver. It integrates the capstan, cylinder,
loading motor driver, and amplifier of each sensor signal that is required for digital video camera systems.
