Note1: Voltage is ground referenced.
Note2: However, do not exceed 6V.
Note3: PCB condition 76.2 x 114.3 x 1.6 mm, Cu 30% (SEMI conforming)
Note4: The power dissipation decreases the reciprocal of the saturated thermal resistance (1/ Rth(j-a)) for each degree (1) that the ambient temperature is exceeded (Ta = 25).




Description

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 TCA62746 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 TCA62746 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.
