This board was designed to allow the user to evaluate all the features available on the ISL81334 and ISL41334 products. The ISL41334 is the full featured version where the QFN package's increased pin count gives the user access to functionality not available on the pin limited ISL81334. The same die is used in both products, so other than minor package effects, evaluating the QFN packaged ISL41334 is a reasonable substitute for evaluating the ISL81334.
By changing jumper positions the user can quickly set the board to evaluate any of the ISL41334’s many modes and features, and the input states can also be set via jumpers.
