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 func-
tions.

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 bright-
ness 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
