It combines ADI's iCoupler digital isolation technology with an integrated isoPower DC-to-DC converter, eliminating the need for any external isolated power supply. The device supports data rates up to 500kbps, operates from a single 3.3V or 5V supply, and provides 2500V rms isolation (UL 1577) with \u00b115kV ESD protection on RS-485 bus pins. Configurable as half-duplex or full-duplex, it supports up to 256 nodes on one bus with open\/short fail-safe receiver inputs and >25kV\/\u03bcs common-mode transient immunity.","working_principle":"The ADM2587E integrates three functional blocks: (1) iCoupler digital isolators using chip-scale transformer technology \u2014 high-speed data crosses the isolation barrier via magnetic coupling through polyimide insulation, providing galvanic isolation; (2) An RS-485 transceiver \u2014 the driver converts single-ended TXD to differential signals (A\/B) compliant with TIA\/EIA-485-A, while the receiver converts differential bus signals back to single-ended RXD; (3) isoPower DC-DC converter \u2014 uses high-frequency switching (approximately 180MHz) to transfer power across the isolation barrier via an integrated transformer, generating the isolated supply for the bus-side circuitry. The back-to-back architecture ensures signal integrity and power isolation in a single package. Thermal shutdown and current limiting protect against fault conditions.","pin_description":"Pin Description(Output pin definitions in table format only; return pure content without derivation or extra elaboration)","application_scenarios":"Application Scenarios (Output pin definitions in table format only; return pure content without derivation or extra elaboration)","alternative_models":"ADM2582EBRWZ (16Mbps high-speed variant); ADM2587EBRWZ-REEL7 (tape & reel packaging); ISO1176T (TI, isolated RS-485, requires external DC-DC); MAX14936 (Maxim, isolated RS-485 without integrated power); Si862x (Silicon Labs, digital isolator only)"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10568","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/comments?post=10568"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10568\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=10568"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=10568"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=10568"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10568"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
