LB8655T
Features
Monolithic Digital IC
Driver for Digital Still Cameras
* 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
