BU91530KVT-M
MAX 445 Segment(89SEGx5COM)
General Description
The BU91530KVT-M is 1/5, 1/4, 1/3 or 1/1 duty
general-purpose LCD driver that can be used for
frequency display in electronic tuners under the control of
a microcontroller. The BU91530KVT-M can drive up to
445 LCD Segments directly. The BU91530KVT-M can
also control up to 9 general-purpose output ports.
These products also incorporate a key scan circuit that
accepts input from up to 30 keys to reduce printed circuit
board wring.
Features
AEC-Q100 Qualified (Note1)
Key input function for up to 30 keys (A key scan is
performed only when a key is pressed.)
Either 1/5, 1/4, 1/3 or 1/1 duty (static)
can be selected with the serial control data.
1/5 duty drive: Up to 445 segments can be driven
1/4 duty drive: Up to 360 segments can be driven
1/3 duty drive: Up to 270 segments can be driven
1/1 duty drive: Up to 90 segments can be driven
Serial Data Control of frame frequency for common
and segment output waveforms.
Serial data control of switching between the segment
output port , PWM output port and general-purpose
output port functions.(Max 9 ports)
Built-in OSC circuit
Integrated Power-on Reset Circuit
No external component
Low power consumption design
Supports Line and Frame Inversion
(Note1) Grade 3
Applications
Car Audio, Home Electrical Appliance,
Meter Equipment etc.

(Note3) Derate by 1.49mW/°C when operating above Ta=25°C (when mounted in ROHM’s standard board).
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.
