Toshiba's storage and electronic components solutions company developed the TB62D787FTG single-line signal input, 24-channel output LED driver IC for play equipment and LED lighting applications.
Like the Toshiba 9-channel output IC TB62D786FTG, the new product integrates a single-wire Manchester encoding interface, and integrates a linear regulator circuit (5V output) with inputs up to 28V and daisy-chained pins for communication data. Therefore, the 3-wire input (one power line, one data line, and one ground line) effectively increases the scalability of the LED driver unit.
In addition, the new communication mode supports switching between 6-channel and 12-channel outputs, improving the compatibility of the new 24-channel output IC with the controller. The IC uses a compact package (VQFN40) with a thermal pad on the back for miniaturization of the LED unit board.
The new product has a built-in single-wire interface with a communication mode that can switch between 6-channel and 12-channel outputs. It has a single-line input (5V system CMOS), a transmission frequency of 0.5MHz to 2MHz, and a built-in linear regulator (7-28V input, 5V output), IC control voltage is 4.5-5.5V (provided by linear regulator circuit or external power supply).
This new range of products and 9-channel output products expand the range of IC options available to customers based on the number of LED luminaires, LED unit size, and location of the target unit.
