BU91501KV-M
Low Duty LCD Segment Drivers for Automotive applications
BU91501KV-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 204 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 support up to 4 general-purpose outputs to control LED devices. It can also support a key scan function that detects a maximum of 30 keys inputs to reduce PCB wiring and to minimize microcontroller size and cost.
