D2006 SY IM B8-8121 No.8084-1/5 
LB8655T 
Features 
 
Actuator driver for digital cameras embedded in one chip. 
(1) Saturation output for AF - Stepping motor (1 phase, 2 phase and 1-2 phase excitation possible) 
(2) Constant current control output for SH 
 
Quick charge and quick discharge circuitry allow the stabilization of response speeds. 
 
Input port 1 allows shutter close control. 
 
When shutter opening control, open-loop constant current control is possible. 
(3) Saturation output for AE - voice coil motor drive 
(4) ZOOM (lens barrel) - Constant voltage DC motor driver (Forward evolution/Reverse evolution/Brake) 
Synchronous actuator driving with zoom is possible.  
 
No standby current consumption (or zero). 
 
2 system power source (VB : for DC motor, VCC : others) 
 
Low saturation output 
 
Built-in thermal protection circuitry 
 
Small, thin package
