MAX22563MAX22566 Evaluates: MAX22563 MAX22566 Evaluation Kits General Description EV Kit Photos The MAX22563MAX22566 evaluation kits (EV kits) provide a proven design to evaluate the MAX22563MAX22566, a family of reinforced, six-channel, galvanic digital isolators in a 20-pin SSOP package. Two types of evaluation boards are available to support different channel direction configurations and selectable output default settings of the MAX22563MAX22566 family. The MAX22565CAEVKIT is fully assembled and tested, and comes populated with the MAX22565CAAP+ (Figure 1). The MAX2256XAEVKIT is a generic board that has U1 unpopulated, allowing to select a device from the MAX22563MAX22566 family (Figure 2). Both evaluation boards support the 20-pin SSOP package type only. See Table 1 for EV kit options. The MAX22163MAX22166 and MAX22663MAX22666 are functionally equivalent to MAX22563MAX22566, but in different package types. The MAX22163MAX22166 come in a 16-pin QSOP and MAX22663MAX22666 in a 16-pin wide SOIC package. The MAX22563MAX22566 EV kits can be used to evaluate the functionality and electrical performance of the entire family of the devices. Figure 1. MAX22565CA EV Kit The EV kits should be powered from two independent isolated power supplies with nominal output voltage in the range from 1.71V to 5.5V. To evaluate the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used. The MAX2256XAEVKIT comes with U1 unpopulated and supports the following digital isolators: MAX22563BAAP+, MAX22563CAAP+, MAX22564BAAP+, MAX22564CAAP+, MAX22565BAAP+, MAX22565CAAP+, MAX22566BAAP+, and MAX22566CAAP+. Note: When ordering the MAX2256XA EV kit, request a sample of the desired MAX22563 MAX22566 isolator IC that can be soldered to the PCB.

Connect the signal/function generator to an input SMA Procedures connector or test point of side A and observe the The MAX22565CA EV kit is fully assembled and ready for isolated signal on the corresponding side B output evaluation. The MAX2256XA EV kit has everything except using an oscilloscope. On the MAX22565CA EV kit, the DUT (U1) installed. The user can install the desired SMA connectors A1A5 and B6 are inputs, and SMA version of the MAX22563MAX22566 family of reinforced, connectors B1B5 and A6 are outputs.
