Programmable VCOM Calibrator with EEPROM and
Output Buffer
ISL24212
The ISL24212 is an 8-bit programmable current sink that can be
used in conjunction with an external voltage divider to generate a
voltage source (VCOM) positioned between the analog supply
voltage and ground. The current sink’s full-scale range is
controlled by an external resistor, RSET. With the appropriate
choice of external resistors R1 and R2, the VCOM voltage range
can be controlled between any arbitrary voltage range. The
ISL24212 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 VCOM 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 VCOM_OUT pin.
The ISL24212 also features an integrated, wide-bandwidth, high
output drive buffer amplifier that can directly drive the VCOM
input of an LCD panel.
The ISL24212 is available in an 10 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.
