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.
