No.09014EAT02
Description
The BD6373GW motor driver provides 6 Full-ON Drive H-bridge channels. The BD6873KN motor driver provides 5 Full-ON
Drive H-bridge channels and 1 Linear Constant-Current Drive H-bridge channel, while the BD6753KV provides 4 Full-ON
Drive channels and 2 PWM Constant-Current Drive H-bridge channels.
Stepping motors can be used for auto focus, and either zoom or iris. A new drive type (lens barrier) is also available. Three types of drivers
for shutter are offered: a simple Full-ON type, a high-precision linear constant current type, or a high-efficiency PWM constant current type,
enabling selection of the ideal solution based on the application.
