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.

Features

• 16-output built-in

: When in detection mode, outputs the detection results via

SOUT.

• Output short detection (OSD) function

: When in detection mode, outputs the detection results via

SOUT.

• Output current setting range

: 2 to 50 mA

× 16-constant current output

: Between outputs:

± 1% (typ.)

Between devices:
