Interface Pin Function
|1||C2N||Positive Terminal of the Flying Inverting Capacitorr 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.|
|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.
|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.
|12||IREF||This is segment output current reference pin.
When external IREF is used, a resistor should be connected between this pin and Vss to maintain the IREF current at a maximum of 30uA.
When internal IREF is used, this pin should be kept NC
|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.
