Low Duty LCD Segment Driver For Automotive COG Application - BU91R63CH-M3BW (New)

BU91R63CH-M3BW is a 1/4, 1/3, 1/2 duty or static COG type LCD driver that can be used for automotive applications and can drive up to 176 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°C and compliant for AEC-Q100, as required for Automotive Application. It has integrated display RAM for reducing CPU load. Also, it is designed with low power consumption and no external component needed. It includes read function for display RAM and command register, wherein it is possible to detect malfunction due to noise. Also a defective mounting of COG can easily be controlled by using pins to measure ITO resistance. It can support LCD contrast adjustment by its EVR function.
