OSHIBA TOSHIBA Bi-CMOS Curr Interface Driv Constant Cur rent Interface Driver
TB62701AN
16 Bit Constant Current LED Driver with Shift Register and Latch Functions
Product Description:
The TB62701AN is specifically designed for LED display applications. The Bi-CMOS device has 16 Bi-polar constant current output channels and includes CMOS shift register and latch functions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-50mA and is held constant across all 16 outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs.
TB62701AN
Features:
* 16 Constant Current Output Channels * Current Programmable from 5-50mA * 5V CMOS Compatible Inputs * Supports up to a 30V LED Supply Voltage Block Diagram:
