Programmable VCOM Calibrator with EEPROM
ISL24201
The ISL24201 provides an 8-bit programmable current sink that
is used in conjunction with an external voltage divider and buffer
amplifier to generate a voltage source that is positioned between
the analog supply voltage and ground. The current sink’s
resolution is controlled by an external resistor, RSET, and the
span of the VCOM voltage is controlled by the voltage divider
resistor ratio and the source impedance of R1 and R2. This
device has an 8-bit data register and 8-bit EEPROM for storing a
volatile and a permanent value for its output. The ISL24201 has
an I2C bus interface that is used to read and write to its registers
and EEPROM. At power-up the EEPROM value is transferred to
the data register and output.
The ISL24201 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.
