説明

The MAX22518 evaluation kit (EV kit) provides a proven design to evaluate the MAX22517–MAX22519 family of self-powered, dual-channel, 3.5kVRMS digital isolators. The EV kit allows easy access to both channels through either terminal blocks or test points. The isolated field-side supply VDDF can also be accessed using the test points. The EV kit includes necessary external components to demonstrate the device’s surge performance (1.2/50µs) up to ±1kV between input and field ground (differential), or up to ±2kV between inputs (common mode).

The MAX22518 EV kit is designed to support all three variants in the MAX22517–MAX22519 family. Jumpers on the logic-side outputs (OUT1L and OUT2L) allow to connect or disconnect the pullup resistors, depending on whether U1 has open-drain or push-pull outputs. The evaluation board comes with the wide-body 8-pin SOIC package type with 5.5mm creepage and clearance. See Table 1 for EV kit details.

The MAX22518 EV kit (MAX22518EVKIT#) is fully assembled and tested, and comes populated with the MAX22518AWA+ (Figure 1). The board also supports the MAX22517AWA+ and MAX22519AWA+, but requires the user to replace U1. See Table 1 and Evaluate MAX22517 and MAX22519 on MAX22518EVKIT# section for details.

The EV kit is powered from a single power supply on the logic side, VDDL, in range from 3V to 5.5V. The field-side supply, VDDF, is generated by the device and has a nomi- nal voltage of 3.3V. The logic-side ground (GNDL) and field-side ground (GNDF) are isolated and can have con- tinuous working voltage difference up to 445VRMS. For evaluating the electrical parameters of the devices without any isolation between the two sides, a common ground can be shared between GNDL and GNDF.

Note: When ordering an EV kit, if the desired device is not the MAX22518AWA+, request samples of the desired MAX22517–MAX22519 IC that can be soldered to the PCB.
