MAX17119 - 10-Channel Scan Driver

General Description

The MAX17119 includes a 10-channel, high-voltage, level-shifting scan driver with a gate-pulse modulation (GPM) feature to shape the corner of the scan-driver output to reduce flicker.

The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.

Key Features

  • a dedicated discharge channel and an integrated voltage detector. When the system shuts down, the voltage detector commands the discharge channel to swing its output to positive supply voltage so as to remove any residual image on the display quickly. The MAX17119 is available in a 28-pin, 5mm x 5mm, thin QFN package with a maximum thickness of 0.8mm for thin LCD panels. Features S High-Voltage Level-Shifting Scan Drivers Logic-Level Inputs +38V to -12V Outputs GPM Feature Discharge Channel S.

MAX17119 19-4952; Rev 0; 12/09 EVAALVUAAILTAIOBNLEKIT 10-Channel Scan Driver for TFT LCD with GPM Function General Description The MAX17119 includes a 10-channel, high-voltage, level-shifting scan driver with a gate-pulse modulation (GPM) feature to shape the corner of the scan-driver output to reduce flicker. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications. The high-voltage level-shifting scan driver is designed to drive the TFT panel gate logic. Its 10 outputs swing from +38V (maximum) to -12V (minimum) and can swiftly drive capacitive loads. There are two positive supply inputs that provide flexibility for system design. The GPM feature is employed to shape the corner of the falling edge of the clock channels.
