Low Duty LCD Segment Driver for Automotive application BU91600FV-M

BU91600FV-M is a 1/4, 1/3, 1/2duty or Static general-purpose LCD driver that can be used for automotive applications and can drive up to 116 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 can control up to 16 general-purpose outputs / 6 PWM output ports for LED backlighting and LED button illumination realizing less flicker by various frequency setting function. It can also support a key scan function that detects a maximum of 20 key inputs to reduce PCB wiring and to minimize microcontroller size and cost. It can support LCD contrast adjustment by its EVR function and TTL compatible input interface is also available, these are well-suited for wide-voltage range of MCUs.
