adm2587ebrwz-reel7

ADM2587E refers to industrial grade isolated RS485/RS422 transceiver series with integrated isolated power supply. BRWZ stands for 20-lead wide-body SOIC surface mount package. REEL7 means standard 7-inch tape-and-reel packaging for automated SMT mass production.

Built on ADI iCoupler magnetic coupling isolation technology and integrated isoPower isolated DC-DC converter, this single-chip device integrates three digital isolation channels, differential bus transceiver circuitry and isolated power unit. No external isolated power module is required to realize galvanically isolated serial communication.

It provides 2500Vrms isolation voltage and common-mode transient immunity higher than 25kV/μs, effectively eliminating communication errors caused by ground potential difference in harsh industrial environments. The logic side supply voltage ranges from 3.0V to 5.5V, compatible with mainstream 3.3V and 5V microcontroller systems. An internal isolated 5V rail is generated to power the bus-side circuitry.

The maximum data transmission rate reaches 500kbps. Hardware pins support switching between full-duplex and half-duplex operation modes, and up to 256 nodes can be connected on one single bus line. The bus pins are equipped with ±15kV HBM ESD protection and surge suppression circuitry, together with bus short-circuit current limiting and thermal shutdown protection. The receiver incorporates fail-safe design under bus open, short and idle conditions to avoid garbled data output. Low quiescent power consumption enables long-term continuous operation for field devices.

Packaged in 20-lead wide SOIC surface mount housing. The widened package dimension complies with safety creepage and clearance requirements for isolation insulation while maintaining a compact footprint to save PCB layout space. Moisture Sensitivity Level is MSL3; all reflow soldering procedures shall be finished within 168 hours after the original vacuum package is opened. Continuous tape reel delivery is adopted to match feeding systems of automatic chip mounters.

The industrial operating temperature range spans -40℃ to +85℃, supporting stable operation inside inverter workshops, power substations, outdoor industrial terminals and other sites with drastic temperature variations and intensive electromagnetic interference. Manufactured with lead-free construction, the component complies with global RoHS environmental directives and UL1577 insulation safety certification for reliable electrical performance. The highly integrated architecture drastically reduces the count of external power, isolation and protection components, simplifying hardware layout and cutting down overall system BOM cost and development cycle.
