BU97930MUV
Low Duty LCD Segment Drivers

BU97930MUV is a 1/4, 1/3duty or Static general-purpose LCD driver that can be used for consumer / battery operated products and can drive up to 108 LCD Segments.
It has integrated display RAM for reducing CPU load. Also, it is designed with low power consumption and no external component needed.
It can support up to 4 general-purpose outputs to control LED devices and can control 1ch LED driver that able to support LED PWM illumination.
Its small QFN package is well-suited for small footprint applications.
