LB8652T
Features
Actuator driver for digital cameras embedded in one chip. (Not supported synchronous driving.)
(1) Saturation output for AF - Stepping motor (2 phase, 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 - VCM or stepping motor can be used. (2 phase, 1-2 phase excitation possible)
(4) ZOOM (lens barrel) - Constant voltage DC motor driver (Normal evolution/Reverse evolution/Brake)
Or saturation output stepping motor (2 phase, 1-2 phase excitation possible)
Applications of various actuators possible.
