Low Duty LCD Segment Driver
for Automotive application
BU91600xxx Series MAX 148 Segments (37SEG x 4COM)
General Description
The BU91600FV-M and BU91600FUV-M are 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 +105C 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.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the
absolute maximum ratings.
