There are sub-windows for each channel (
Channel 1
and
Channel 2
) and the
Device
sub-window for shared
features. The
Device
window covers features for the device such as thermal, faults, fault timer settings, PWM
frequency, Limp Home mode, 5VD measurements, fault resets, sleep mode, and register reads. Each channel
window sets the LED current (Analog Current), switching frequency (On Time), the PWM duty cycle (PWM),
PWM source (Internal or External UDIM pin), fault response settings, and if the channel is enabled or not. The
channel windows also have information about input voltage (V
IN
) and output LED voltage (LED) measurements.
There are also the associated status information such as fault flags that are tied to each channel.
