Low Duty LCD Segment Driver for Automotive application - BU91797MUF-M

BU91797MUF-M is a 1/4 duty general-purpose LCD driver that can be used for automotive applications and can drive up to 144 LCD Segments. This product can support VA LCD displays, which has better optical performance with higher LCD voltage driving and higher frame frequency driving. It can support operating temperature of up to +105℃ and is qualified for AEC-Q100 Grade2, as required for automotive applications. It has integrated display RAM for reducing CPU load. Also, it is designed with low power consumption and no external component needed. Wettable flank QFN package is suitable for small footprint applications and provides significant advantages in inspectability and solder joint reliability.
