PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD161644
241 OUTPUT GATE DRIVER WITH POWER SUPPLY FOR TFT-LCD GATE DRIVER
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
