LB8653T, LB8653FN

No.7982-2/14

• 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.
