16-Output Constant Current LED Driver with Output Open/Short Detection
The TCA62746 series are LED drivers with sink type constant
circuit output, making them ideal for controlling LED modules
and displays.
The current value of the 16-output is configurable using one
external resistor.
In addition, these drivers are equipped with a function for
detecting the output voltage when the output load LEDs open or
short, and which then outputs the result as serial data.
These drivers consist of a 16-constant current output block, a
16-bit shift register, a 16-bit latch and a 16-bit AND-gate.
The suffix (G) appended to the part number represents a Lead
(Pb)-Free product.
