OSHIBA TOSHIBA Bi-CMOS Curr Interface Driv Constant Cur rent Interface Driver
TB62707F
8 Bit Constant Current LED Driver with Latch Function
Product Description:
The TB62707F is specifically designed for LED display applications. The Bi-CMOS device has 8 Bi-polar constant current output channels and includes CMOS latch function. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-90mA and is held constant across all 8 outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs.
