The RTQ6749 is an I2C interface programmable power management IC. The IC includes two synchronous boost converters for PAVDD and VGH, one synchronous NAVDD buck-boost, one VGL charge pump, one high performance VCOM with 8-bit Calibrator and one RESET voltage detector. With available in a WQFN-32L 5x5 package, this device is suitable for automotive TFT-LCD panel.
The IC can operate from 2.5V to 5.5V input voltages. High switching frequency operation prevent that the switching noise to interfere AM band. Current-limit functions are provided for all internal- switch converters, and output-fault shutdown protects all converters against output-fault conditions, and output the FAULT signal to communicate with automotive computer. Programmable soft-start functions for all output voltage to limit input inrush current during startup. The recommended junction temperature is -40°C to 150°C, and the ambient temperature is -40°C to 105°C.
