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
