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.

7. Power-ON Reset (POR)
The POR circuitry resets all the internal data to the default values upon powering up the TB62D612FTG in order to
ensure proper device operation.
The POR circuitry is only activated when Vcc rises from 0 V. To reactivate POR, Vcc must be powered down to 0 V. The
internal data hold voltage is guaranteed after Vcc has once reached or exceeded 3.0 V.

8. Thermal Shutdown (TSD)
When the die temperature reaches 150 °C , the thermal shutdown circuit is tripped, switching the constant-current outputs to off.
The constant-current outputs are automatically turned on when the temperature cools past the shutdown threshold.
TSD trip temperature: 150 °C to 180 °C
TSD recovery temperature: 30 °C below the TSD trip temperature
*Please avoid positively using TSD because TSD is a detecting function of the product.
