GMT/致新 G2790BK11U-K TQFN4X4-32 带电荷共享功能的TFT-LCD 10-CH电平移位器

General Description
The G2790B is a 10-CH high voltage level shifter with charge sharing functions for TV and monitor LCD applications.
It converts logic level signals from Timing Controller (T-CON) to high level signals used by the LCD panel. The outputs are switching from VGL_GOP to VGH, with capacitive loads up to 4.7nF.
The G2790B generates reset function. Once XAO reaches reset level, output channels will pulled to VGH.
In addition to, the G2790B also generates OCP&SCP function. Once OCP&SCP reaches fault conditions, output channels will be Hi-Z.
The G2790B features extensive protection functions that include OCP, SCP, OTP. It is available in a TQFN4X4-32 package.
