View Datasheet Manufacturer Site View Pricing & Stock

BU97520AKV-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 276 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 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. It can also support a key scan function that detects a maximum of 30 key inputs to reduce PCB wiring and to minimize microcontroller size and cost. TTL compatible input interface is also available, these are well-suited for wide-voltage range of MCUs.
