Setting the LED String Current with R ILED and ISTR
The MSL3163/4 features 16 current sink outputs, rated at 40V, each designed to sink up to 100mA peak. Limit average
current to 60mA if the PCB copper around the MSL3163/4 is the only heat sink employed. The maximum string current,
I ILED , for all 16 LED string inputs is set by a single external resistor, R ILED , placed from ILED to GND, whose value is determined
using:
R ILED =
762
I ILED .
For example, a full-scale LED current of 60mA returns R ILED = 12.7k Ω . The current for all LED strings is reduced from its full-
scale value with 8-bit resolution using ISTR, the String Current Control register 0x0F.
