The MAX22440-MAX22442 evaluation kits (EV kits) provide a proven design to evaluate the MAX22440-MAX22442, MAX22840-MAX22842, and MAX22880-MAX22882, a family of reinforced, ultra-low-power, four-channel digital isolators in a 16-pin QSOP, 16-pin WSOIC, or 20-pin SSOP package, respectively. Two types of evaluation boards are available to support all variants in the family in 4/0, 3/1, or 2/2 channel configurations. The MAX22441CEEVKIT# is fully assembled and tested, and it comes populated with the MAX22441CAEE+ (Figure 1). The MAX2244XEEVKIT# is a generic board that has U1 unpopulated, allowing the user to select a device from the MAX22440-MAX22442 family (Figure 2). Both evaluation boards only support the 16-pin QSOP package type. See Table 1 for EV kit options.

The MAX22840-MAX22842 and MAX22880-MAX22882 are functionally equivalent to the MAX22440-MAX22442, but in a 16-pin WSOIC and 20-pin SSOP package, respectively. The EV kits can be used to evaluate the functionality and electrical performance of the MAX22840-MAX22842 and the MAX22880-MAX22882.

The EV kits should be powered from two independent isolated power supplies with nominal output voltage in the range of 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used.

The MAX2244XEEVKIT# comes with U1 unpopulated and supports the following digital isolators: MAX22440CAEE+, MAX22440FAEE+, MAX22441CAEE+, MAX22441FAEE+, MAX22442CAEE+, and MAX22442FAEE+.
