TB62D612FTG

24-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply Voltage Operation

The TB62D612FTG is a constant-current driver designed for LED and LED

display lighting.

The TB62D612FTG incorporates twenty-four channels of seven-bit PWM

dimming controllers and constant-current drivers. Twenty-four constant-current

drivers are divided into three blocks, each consisting of three drivers, and the

output current of each can be independently adjusted by the relevant external

resistor.

The TB62D612FTG is controlled using the SDA and SCLK input signals, and

capable of high-speed data transfers.

The TB62D612FTG can be set address with ID terminal. (Up to 64 address)

High-speed processing is capable by applying Bi-CMOS process.

The TB62D612FTG operates with a supply voltage of 3.3 V or 5 V.
