DEMO MANUAL DC2442A

The LTpowerPlay GUI divides information into separate 

panes in the window. On the left is the System Tree pane, 

displaying a list of all Linear Technology devices identified 

on the I

2

C bus. For a single LTC4282 device, the tree is 

small, but if other supported devices are present on the 

I

2

C bus, LTpowerPlay will add them. Click on a device in 

this list to selectively access it. Information in other panes 

pertains to the selected device.

To the right of the system tree is the Configuration Reg-

ister pane displaying all of the configuration registers 

available on the selected device. This view shows all of 

the writable user-configurable RAM registers, and the GUI 

offers clickable buttons and fields to edit the information 

in these registers.

Note:

 Ensure that you set the resistor value of 62.5µΩ in 

the Setup tab before viewing register data to get correct 

current readout.
