ESPECIFICACIONES
Función interfaz Pin
| No. | Símbolo | Función |
|---|---|---|
| 1 | C2P | Positive Terminal of the Flying Inverting CapacitorNegative Terminal of the Flying Boost CapacitorThe charge-pump capacitors are required between the terminals. They must be floated when the converter is not used. |
| 2 | C2N | |
| 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 | I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin inapplication 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. |
