DESCRIPTION

The µPD161644 is a TFT-LCD gate driver with power supply for TFT-LCD driver. Because this gate driver has a level shift circuit for logic input, it can output a high gate scanning voltage in response to a CMOS-level input. This ICs can generate the levels which TFT-LCD driver need, from 2.7 V.

FEATURES

•High breakdown voltage output (VDD1-VSS3= 40 V MAX.)

•2.7 V CMOS level input

•Number of output: 241 output selectable

•To generate 4 levels from single voltage input

•To integrate regulator circuit for source driver

•Mode setting from source driver: Serial I/F or pin control

•On-chip VCOM driver

•On-chip gate output low-level selector
