The ISL24005 is divided into two sets of seven generators: one is designed to cover the range from VREFL_L to VREFL_H, and the other is designed to cover the range from VREFU_L to VREFU_H. The VCOM calibrator is the sink-current output that attaches to an external voltage divider. The desired VCOM setting can be adjusted by the I2C interface. ISL24005 is available in the 32 Ld Thin QFN package and is specified for operation over the -40°C to +85°C temperature range.
