REGISTER AnD ConTRoL TAB
The register and control tab provides a detailed view of the
LTC2943 device registers as well as provides convenient
means to read and write to them.

Address/I C Status
The write address for the LTC2943 is C8h and the read
address is C9h. If an error occurs while reading from
2
the LTC2943, the I C status will display an error and the
corresponding LED will turn red. Otherwise, the status is
good and the LED remains green.

Sense Resistor
By default, the demo board is populated with a 100mΩ
sense resistor to measure a maximum full-scale current of
500mA. If a different full-scale value current is desired, the
sense resistor can be easily replaced and the correspond-
ing resistor value can be set in the interface. Every time a
new resistor value is entered, the interface will recalculate
a suggested prescalar and q
it in the "LSB Information" section.
