5-Channel System Lens Driver
for Digital Still Cameras
BD6370GUL
General Description
The BD6370GUL is a motor driver that integrates 3
Full-ON or Constant-Voltage type H-bridges, 1
Constant-Voltage or Linear Constant-Current or
Full-ON type H-bridge and 1 Linear Constant-Current
type H-bridge. The device can drive one stepping
motor for auto focus, and DC motors for zoom and iris.
It is therefore possible to drive another stepping motor
for either zoom or iris, because it has the system to
drive 6-channel H-bridges exclusively.
Features
 Low ON-Resistance Power CMOS Output
 Drive Mode Switch Function
 Serial Interface 3-line Bus Control
 Exclusive 6-Channel Drive Function
 6-Bits D/A Converters for Constant-Voltage
and Constant-Current Control
 High-Precision (±5%) Constant-Voltage Driver
 High-Precision (±3%) Linear Constant-Current
Driver
 Both Constant-Voltage Drive Block and
Constant-Current Drive Block feature Phase
