High-Voltage Level-Shifting Scan Driver
Dual, High-Voltage Scan Driver for TFT GOFF Rapid Discharge Function (DISH Input) The DISH input controls a switch between GOFF and AGND. When DISH is pulled below ground by at least 1V, VGOFF is rapidly discharged to AGND. Typically DISH is capacitively coupled to VDD so that if VDD falls suddenly, VGOFF is quickly discharged to AGND. Thermal-Overload Protection The thermal-overload protection prevents excessive power dissipation from overheating the device. When the junction temperature exceeds TJ = +160°C, a thermal sensor immediately shuts down the scan driver outputs. The outputs are set to high impedance. Once the device cools down by approximately 15°C, the device reactivates. The thermal-overload protection protects the IC in the event of overheat conditions. For continuous operation, do not exceed the absolute maximum junction temperature rating of TJ = +150°C. Applications Information Power Dissipation An ...
