LED Overview
The
MAX32600
provides the capability to drive multiple LEDs simultaneously with high output current drive and integrated closed loop current control. Depending
on the application, one or more of the various LED configurations will be used. Each particular LED configuration requires specific organization of components both
within and external to the chip. The simplest LED configurations require one DAC, one op amp, and one I/O pair on the
MAX32600
. External components—an LED
and a sense resistor (Rs)—are also needed, necessitating the use of additional
routing resources as well.
Note

for a detailed mapping of
MAX32600
multiplexed function locations. Functional priority distinction is included in the mapping.
