Overview
The LB8649W integrates the actuator drivers required by digital cameras on a single chip.
Features
Integrates the actuator drivers required by digital cameras on a single chip. 1. Shutter drive ("SH") /AE system constant current output stepping motor or two VCM drivers 2. Zoom system constant voltage output stepping motor or DC motor driver (forward/reverse/brake) 3. AF system constant voltage output stepping motor driver
Zero standby mode current consumption (allows batteries to be connected directly) Four independent power supply systems (SH/AE, AF, zoom, and input logic systems) Low-voltage drive (allows operation from two NiMH batteries) Built-in thermal protection circuit
