ISL3331EVAL1Z Evaluation Board
The ISL3331EVAL1Z evaluation board is RoHS compliant, and provides a quick and easy method for evaluating this Dual Protocol IC. The evaluation board also accommodates the ISL3333; see the “ISL3333EVAL1Z User’s Manual” for details.
This board was designed to allow the user to evaluate all the features available on the ISL3330 and ISL3331 products. The ISL3331 is the full featured version (see “Key Features” in next section), where the QFN package’s increased pin count gives the user access to functionality not available on the pin limited ISL3330. The same die is used in both products, so other than minor package effects, evaluating the QFN packaged ISL3331 is a reasonable substitute for evaluating the ISL3330.
By changing jumper positions the user can quickly set the board to evaluate any of the ISL3331’s many modes and features, and the input states can also be set via jumpers.
Refer to the ISL3331 data sheet for complete details regarding the functions and features of this device. These dual protocol ICs feature many modes, so studying the device’s truth-table along with its operating circuits and detailed description is the best way to gain an understanding of how the part works.
