| 1 | C2N | Positive Terminal of the Flying Inverting Capacitor Negative Terminal of the Flying Boost Capacitor The charge-pump capacitors are required between the terminals. They must be floated when the converter is not used. |
| 2 | C2P | |
| 3 | C1P | |
| 4 | C1N | |
| 5 | VBAT | Power Supply for DC/DC Converter Circuit This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used. |
| 6 | NC | .No connection |
| 7 | VSS | Ground of Logic Circuit .This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground |
| 8 | VDD | Power Supply for Logic .This is a voltage supply pin. It must be connected to external source |
| 9 | #RES | Power Reset for Controller and Driver .This pin is reset signal input. When the pin is low, initialization of the chip is executed |
| 10 | SCL | Host Data Input/Output Bus When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. When I2C mode is selected, D2 & D1 should be tired together and serve as SDAout & SDAin in application and D0 is the serial clock input SCL. |
| 11 | SDA | |
| 12 | IREF | Current Reference for Brightness Adjustment .This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 12.5μA |
| 13 | VCOMH | Voltage Output High Level for COM Signal .This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS |
| 14 | VCC | Power Supply for OEL Panel This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used |
