Monolithic Digital IC
LB8649W
Digital Camera Motor Driver
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
