MAX22518 Evaluation Kit Evaluate: MAX22517MAX22519 General Description Features The MAX22518 evaluation kit (EV kit) provides a proven Self-Generated Isolated Field-Side Supply V DDF design to evaluate the MAX22517MAX22519 family of 2 Unidirectional Channels with Input Charge Pumps self-powered, dual-channel, 3.5kV digital isolators. RMS (MAX22517 and MAX22518) and Open-Drain The EV kit allows easy access to both channels through Outputs (MAX22518 and MAX22519) either terminal blocks or test points. The isolated field-side Surge and Short Protection with Onboard supply V can also be accessed using the test points. DDF Components The EV kit includes necessary external components to 24VAC Short Protection demonstrate the devices surge performance (1.2/50s) 1kV Line-to-Ground and 2kV Line-to-Line Surge up to 1kV between input and field ground (differential), Tolerance (1.2/50s Waveform) or up to 2kV between inputs (common mode). Terminal Blocks and Test Points for Easy Connection The MAX22518 EV kit is designed to support all three to External Equipment variants in the MAX22517MAX22519 family. Jumpers on the logic-side outputs (OUT1L and OUT2L) allow to Single Logic-Side Supply V , Range from 3V DDL connect or disconnect the pullup resistors, depending to 5.5V on whether U1 has open-drain or push-pull outputs. The Guaranteed Up to 3.5kV Isolation for 60s RMS evaluation board comes with the wide-body 8-pin SOIC -40C to +125C Temperature Range package type with 5.5mm creepage and clearance. See Table 1 for EV kit details. Proven PCB Layout 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. Ordering Information appears at end of data sheet. The EV kit is powered from a single power supply on the logic side, V , in range from 3V to 5.5V. The field-side DDL supply, V is generated by the device and has a nomi- DDF, 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 445V . For RMS 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 MAX22517MAX22519 IC that can be soldered to the PCB. 319-100553 Rev 2 8/20MAX22518 Evaluation Kit Evaluate: MAX22517MAX22519 Figure 1.
