LB8652T

LB8652LP

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.
