Low Duty LCD Segment Drivers for Automotive applications - BU91510KV-M
BU91510KV-M is a 1/4 or 1/3 duty general-purpose LCD driver that can be used for automotive applications and can drive up to 216 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 can control up to 6 general-purpose outputs / PWM output ports for LED backlighting and LED button illumination realizing less flicker by various frequency setting function. TTL compatible input interface is also available, these are well-suited for wide-voltage range of MCUs.
