LCD Segment Drivers

Standard

Segment Drivers

BU9795AKV/FV/GUW,BU9794AKV,BU97950FUV/KS2

No.11044EBT06

●Description

ROHM standard function segment driver series achieve “Ultra-Low power consumption”. Also these drivers need not

external components. And this driver series is very simple that only has segment driver function. So, these driver series are

very suitable to add in LCD display function for various applications.

●Features (BU9795AKV/FV/GUW, BU9794AKV)

1) 3wire serial interface

2) Integrated RAM for display data (DDRAM)

3) Power supply circuit for LCD driving

1/2, 1/3Bias selectable

1/4Duty

Integrated Buffer AMP

4) Integrated Oscillation circuit

5) Integrated Power-on Reset circuit

6) No external components

7) Support blink function

8) Support standby mode

9) Low voltage / Ultra low power consumption design

10) Support unity voltage supply (BU9795AKV/FV/GUW)

11) Support Independent power supply circuit for LCD driving (BU9794AKV)

●Features (BU97950FUV/KS2)

1) 2wire serial interface

2) Integrated RAM for display data (DDRAM)

3) Integrated Power supply circuit for LCD driving

1/4 Bias 1/8 Duty

Integrated Buffer AMP

4) Integrated Oscillation circuit

5) Integrated Power-on Reset circuit

6) No external components

7) Support standby mode

8) Low voltage / Ultra low power consumption design
