Intelligent, Constant Current, 7 segment LED numeric display decoder/driver. For use with common anode configuration numeric displays.
The TB62709N/F is an intelligent Constant Current LED display driver designed specifically for seven segment LED display applications. The stand alone device includes all of the decode, multiplex and driver circuitry necessary to control up to four seven segment LED digits. All of the information required to program up to four LED digits is input serially including a 16 step brightness control. Expansion beyond four digits is possible with a cascade connection to a second device. The device automatically refreshes and maintains the displayed information.
