Ordering number : EN7896D
LB8652T
LB8652LP
Monolithic Digital IC
Driver for Digital Still Cameras
Features
• Actuator driver for digital camera built into one chip (no simultaneous drive)
(1) Saturation output for AF - stepping motor (two-phase, 1 - 2 phases excitation possible)
(2) Constant current control output for SH - VCM
• Response speed stabilized by means of a rapid charge circuit and rapid discharge circuit
• Shutter close control possible with the input one-port
• Current setting possible separately for the shutter “OPEN” and “CLOSE”
(Open loop control for the shutter “OPEN”)
(3) Saturation output for AE - VCM or stepping motor applicable (2-phase, 1 - 2 phases excitation possible)
(4) Constant-voltage output for ZOOM - DC motor (forward/reverse/braking) or saturation output stepping motor
(two-phase, 1 - 2 phases excitation possible)
• Applications of various actuators possible.
