Interface Definition
| NO. | Symbol | Function |
|---|---|---|
| 1 | VLSS | This is an analog ground pin. It should be connected to VSS |
| 2 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin.When charge pump is enabled, a capacitor should be connected between this pin and VSS |
| 3 | VCOMH | The pin for COM signal deselected voltage level. A capacitor should be connected between this pin and VSS |
| 4 | IREF | This is segment output current reference pin. A resistor should be connected between this pin and VSS to maintain the IREF current at a maximum of 30 uA. |
| 5 | SDA | IIC data input pad. |
| 6 | SCL | IIC clock input pad |
| 7 | NC | NO CONNECTION |
| 8 | RES# | Power Reset for Controller and Driver This pin is reset signal input. When the pin is low, initialization of the chip is executed. |
| 9 | VSS | round of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground. |
| 10 | VDD | Power Supply for Logic This is a voltage supply pin. It must be connected to external source. |
| 11 | 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. |
| 12 | 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. |
| 13 | C1N | 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 |
