6-Channel System Lens Driver
for Digital Still Cameras
BD6753KV
General Description
The BD6753KV is a motor driver that integrates 4
Full-ON type H-Bridges and 2 PWM Constant-Current
type H-bridges. The device is intended to drive two
stepping motors for auto focus system, either zoom or
iris. It is also available for the new system like a lens
barrier.
Features

Charge Pump for the High-Side DMOS Gate
Drive Mode Switch Function
Three wire serial Interface
Peak Current Control for
PWM Constant-Current Driver
Under Voltage Locked Out Protection
& Thermal Shut Down Circuit

Connecting 0.01μF to 0.1μF capacitors between the CP1 and CP2, CP3 and
CP4, and VG and GND pins generate a VG voltage of approximately VM1 +
(VCC x 2). Use caution to ensure that the voltage difference between VG and
VM is 4.5V or higher, and that the VG voltage does not exceed the absolute
maximum rating of 18V, especially BST voltage direct input.
