LB8655T Datasheet, PDF (1/5 Pages) Sanyo Semicon Device – Monolithic Digital IC Driver for Digital Still Cameras

Ordering number : EN8084A
LB8655T ^{Monolithic Digital IC}
Driver for Digital Still Cameras
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
