MAX17061 Evaluation Kit/Evaluation System
The MAX17061 can be configured to one of any 256
steps of brightness control. To set the brightness, slide
the Brightness Control track bar to the desired posi-
tion, from 0 to 255. The track-bar position is then dis-
played in the Brightness Level group box.
The MAX17061’s device control register controls the
operating mode of the backlight controller and backlight
on/off states. The MAX17061 operating modes can be
configured according to the bit settings shown in Table 1.

The MAX17061’s fault/status read-only register monitors
the backlight controller’s operating state. This register
detects the backlight on/off state, whether one or two
LED output channels are shut down, overcurrent condi-
tions, and thermal faults. When a fault is detected, the
corresponding bit is changed from logic 0 to logic 1 and
the font color is changed to red. Refer to the MAX17061
IC data sheet for more information regarding the
fault/status register.
The ID Register group box provides the manufacturer
and silicon revision information for the MAX17061 IC.
This information is read upon initial startup.
There are two methods for communicating with the
MAX17061, through the normal user interface (Figure
1), or through the SMBus commands available by
selecting the Interface Diagnostic Window menu item
