NAME
FUNCTION
1
OUT
Adjustable Sink-Current Output. OUT connects to the resistive voltage-divider between AVDD and GND that sets
the VCOM voltage. IOUT lowers the divider voltage by an adjustable amount. See the SET pin description.
2
AVDD
High-Voltage Analog Supply. Bypass to GND with a 0.1F capacitor.
3VDD
3.6V Regulator Output. VDD provides the supply voltage to the entire IC. VDD is not for external use. Bypass to
GND with a 0.1F capacitor.
4
GND
Ground. Connect to system ground.
5HV
EEPROM High-Voltage Programming Supply. Bypass to GND with a 0.1F capacitor. Connect this pin to the TFT
LCD VGON supply. VGON should be between 16.1V and 28V. The HV pin supplies the power for the internal
EEPROM writing cycle. The internal writing circuits are disabled when HV is less than 15.6V (typ).
6
SDA
I2C-Compatible Clock Input
7
SCL
I2C-Compatible Serial Bidirectional Data Line
8
SET
Full-Scale Sink-Current Adjustment Input. Connect a resistor, RSET, from SET to GND to set the full-scale
adjustable sink current. The full-scale adjustable sink current is equal to:
IOUT is equal to the current through RSET.
