MAX22518EVKIT#

MAX22518EVKIT# is a MAX22518 evaluation kit (EV kit) that 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 the 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 (MAX22518EVKIT#) is fully assembled and tested, and comes populated with the MAX22518AWA+. The board also supports the MAX22517AWA+ and MAX22519AWA+, but requires the user to replace U1.

• Self-generated isolated field-side supply VDDF
• 2 unidirectional channels with input charge pumps (MAX22517 and MAX22518)
• Open-drain outputs (MAX22518 and MAX22519)
• Surge and short protection with onboard components: 24VAC short protection
• ±1KV line-to-ground and ±2KV line-to-line surge tolerance (1.2/50μs Waveform)
• Terminal blocks and test points for easy connection to external equipment
• Single logic-side supply VDDL, range from 3V to 5.5V
• Guaranteed Up to 3.5KVRMS isolation for 60s
• Temperature range from -40°C to +125°C
• Proven PCB layout
