Enables simultaneous operation of both focus and iris.
Focus
Shutter
Iris
When “MD1” is not used.
(Requires 4 input ports.)
Not enable the simultaneous operation.
When “MD1” is used.
(Requires 5 input ports.)
Parallel control with 4 or 5 input ports.
Two power supply systems.
Supports low voltage drive (2.2Vmin).
Low saturation output (Vsat = 0.3Vtyp at IO = 300mA).
Current dissipation in stand-by state is 0 (zero).
Built-in overheat protection circuit.
Small and thin package. TSSOP24 (225mil) for LB8653T and VQFN44 (6.0×6.0) for LB8653FN.
