Programmable VCOM Calibrator with EEPROM ISL24202IRTZ
The ISL24202 is an 8-bit programmable current sink that can be used in conjunction with an external voltage divider to generate a voltage source (VsubCOM/sub) positioned between the analog supply voltage and ground. The current sinks full-scale range is controlled by an external resistor, RsubSET/sub. With the appropriate choice of external resistors Rsub1/sub and Rsub2/sub, the VsubCOM/sub voltage range can be controlled between any arbitrary voltage range. The ISL24202 has an 8-bit data register and 8-bit EEPROM for storing both a volatile and a permanent value for its output, accessible through a single up/down counter interface pin (CTL). After the part is programmed with the desired VsubCOM/sub value, the Counter Enable pin (CE) can be grounded to prevent further changes. On every power-up the EEPROM contents are automatically transferred to the data register, and the pre-programmed output voltage appears at the VsubOUT/sub pin.brbr The ISL24202 can be used with a high output drive buffer amplifier, which allows it to directly drive the VsubCOM/sub input of an LCD panel.brbr The ISL24202 is available in an 8 Ld 3mm x 3mm TDFN package. This package has a maximum height of 0.8mm for very low profile designs. The ambient operating temperature range is -40°C to +85°C.
