Product Overview

The ISO7831FDWWR from Texas Instruments is a high immunity, 5.7KVrms, high performance, 8000VPK reinforced triple 2/1 digital isolator in 16 pin WSOIC package. This device has reinforced isolation certifications according to VDE, CSA, TUV and CQC. It provides high electromagnetic immunity and low emissions at low power consumption while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by silicon dioxide insulation barrier. It comes with enable pins which can be used to put respective outputs in high impedance for multi-master driving applications and to reduce power consumption. If input power or signal is lost, the default output is low for ISO7831F device. Used in conjunction with isolated power supplies, it helps prevent noise currents on a data bus or other circuits from entering local ground and interfering with or damaging sensitive circuitry. It is used in power supplies, solar inverters & hybrid electric vehicles.
  • Signalling rate up to 100Mbps
  • Wide supply voltage range from 2.25V to 5.5V
  • Low power consumption of 1.7mA per channel at 1Mbps
  • Low propagation delay of 11ns (5V supplies)
  • Robust electromagnetic compatibility (EMC), system level ESD, EFT and surge immunity
  • Low emissions, isolation barrier life of greater than 40 years
  • Two forward and one reverse direction channels
  • 2.25V to 5.5V level translation
  • Industry leading CMTI (min) of ±100KV/µs
  • Operating temperature range from -55°C to 125°C

Applications

Signal Processing, Industrial, Automation & Process Control, Motor Drive & Control, Medical

Warnings

This device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
