UPD161644 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.
UPD161644 Key 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 V driver
- On-chip gate output low-level selector
