Maxim Integrated MAX25222 Automotive 4-Channel TFT-LCD Power IC provides symmetrical positive analog voltage (AVDD) and negative NAVDD supplies as well as VGON and VGOFF gate supplies. In addition, a VCOM buffer with output voltage range above and below ground and a temperature measurement block are integrated. The MAX25222 includes non-volatile memory so that the values of all outputs can be calibrated for the lifetime of the device, with a five-time maximum. Programming is carried out using the built-in I2C interface, which can also be used to read back diagnostic information. A stand-alone mode is available after the device has been programmed.
