Low Duty LCD Segment Driver

for Automotive application

BU91520KV-M

MAX 276 Segments (69SEG × 4COM)

General Description

Key Specifications

The BU91520AKV-M is 1/4 or 1/3-Duty general-purpose

LCD driver that can be used for automotive applications.

It can support operating temperature of up to +105°C

and qualified for AEC-Q100 Grade2, as required for

automotive applications..

It can drive up to 276 LCD Segments directly. It can

control up to 6 general-purpose output ports. It can also

support a key scan function that detects a maximum of

30 key inputs.
