The TPS65191 is a triple high-voltage scan driver to drive an ASG (amorphous silicon gate) circuit on TFT glass. Each single high-voltage scan driver receives logic-level inputs of CPVx and generates two high-voltage outputs of CKVx, CKVBx. The device receives a logic-level input of STV and generates a high-voltage output of STVP. These outputs are swings from Voff (–28 V) to Von (35 V) and are used to drive the ASG circuit and charge/discharge the capacitive loads of the TFT LCD. In order to reduce the power dissipation of device, a charge-share function is implemented. The device features discharge function, which shorts Voff to GND in order to shut down the panel faster when the LCD is turned off.
