LCD 驱动器 15Ch Lavel Shifter for Large Size TVs
The TPS65196 provides a highly integrated level shifter solution intended for TV and monitor applications using GIP technology. The device features a built-in state machine that generates 14 output signals from the five input signals provided by the timing controller T-CON. In addition, the TPS65196 generates a signal to discharge the display panel during power-down.
To ensure proper start-up of the LCD panel, the TPS65196 includes a programmable soft-start feature that ramps the CLK output current from zero to its maximum value during the initial frames after power-up.
Level shifter outputs are forced to a safe state VGL during abnormal panel operation, which is indicated by the T-CON using the EO and GST signals. The IC is also placed in the same safe state if it gets too hot. Normal behavior restarts automatically synchronized to the start of the next frame when the device temperature is cool enough for safe operation.
