DESCRIPTION

The μ PD168103A is the motor driver IC with IRIS control circuit, operational amplifier and 4-ch H-bridge output. Smooth operation is possible for IRIS control with linear method.

The package is 48-pin thin type QFN and then it helps reduce the mounting area and height.

The μ PD168103A is suitable for the lens drive of a camcorder, DSC, etc.

FEATURES
