Datasheet Low Duty LCD Segment Driver For Automotive COG Application BU91R63CH-M Max 176 segments (SEG44 x COM4) General Description BU91R63CH-M 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. 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, which make it possible to detect malfunction due to noise. Also a defective mounting of COG can easily be controlled by using pins to measure ITO resistance.
