Overview
The LC898111AXB is Optical Image Stabilization (OIS) system control LSI for smartphone camera modules.
The LSI have built-in digital signal processing circuits, such as a 2ch saturation H-Bridge Driver and a Flexible Filter circuit, and control VCM type actuators.
The LC898111AXB is identical LSI except for the dimensions, i.e.
XB has WLP thickness, max. 0.69 mm with B/C.
