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.
Features:
• 16 Constant Current Output Channels
• Current Programmable from 5-50mA
• 5V CMOS Compatible Inputs
• Supports up to a 30V LED Supply Voltage

"H" output off, "L" : latch data = "H" then output on, latch data = "L " then output off
The register which connects between R-EXT and GND sets the constant output current.
