Product Overview

The MXL1535ECWI+ is a +3V to +5V, 2500Vrms isolated RS485/RS422 transceiver with ±15kV ESD protection in 28 pin WSOIC package. This full duplex transceiver provides2500Vrms of galvanic isolation between RS485/RS422 side & processor or control logic side. This device allows fast, 1000Kbps communication across an isolation barrier when the common-mode voltages (i.e. the ground potentials) on either side of barrier are subject to large differences. Isolation is achieved through integrated high voltage capacitors. It features a 420KHz transformer driver that allows power transfer to the RS-485 side using an external transformer. It includes one differential driver, one receiver and internal circuitry to send the RS485 signals and control signals across isolation barrier (including the isolation capacitors). It is used in isolated RS485 systems, systems with large common-mode voltages and telecommunications systems.
  • Supply voltage range is 4.5V to 5.5V
  • Operating temperature range from 0°C to 70°C
  • Pin-selectable slew-rate limiting controls EMI, function/pin compatible to LTC1535
  • Hot-swap protected driver-enable input
  • 1/8 unit receiver load allowing 256 devices on bus
  • ±15KV ESD protection using HBM
  • Undervoltage lockout
  • Isolation-barrier fault detection
  • Short-circuit protected, thermal shutdown
  • Open-line and shorted-line fail-safe receiver inputs
