EVAALVUAAILTAIOBNLEKIT
Dual, High-Voltage Scan Driver for TFT LCD
General Description
The MAX17109 includes two high-voltage, level-shifting
scan drivers for TFT panel integrated gate logic. Each
scan driver has 2 channels that switch complemen-
tarily. The scan driver outputs swing from +40V to
-30V and can swiftly drive capacitive loads. To save
power, the scan driver’s complementary outputs share
the charge of their capacitive load before they change
states.
The MAX17109 is available in a 32-pin, 5mm x 5mm,
thin QFN package with a maximum thickness of 0.8mm
for ultra-thin LCD panels.
Applications
Notebook Computer Displays
LCD Monitor and TV Panels

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
