TB62709NG datasheet

Description

The TB62709NG and TB62709FG are multifunctional, compact, 7-segment LED display drivers. These ICs can directly drive 7-segment displays and individual LEDs, and can control either a 4−digit display with decimal points, or 32 individual LEDs. These ICs can also be used with common−anode displays. Their outputs are constant current, the ampere levels at which are set using an external resistor.
