    Overview

    Development and manufacturing environments contain many variables that may be hazardous to the proper operation and longevity of development tools, such as noise, electrical spikes, transient overvoltages, and ground loops. With its line of isolators, comprising the JTAG, SWD, and USB Isolator, SEGGER offers target-side and host-side electrical isolation for the Flasher, J-Link, and J-Trace families.

    JTAG Isolator

    The JTAG Isolator can be connected between J-Link or Flasher and any Arm board that uses the standard 20-pin JTAG Arm connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application (galvanic isolation). It is also useful to protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another typical field of application is the development of products with sensors or other analog circuitry, in which case the target hardware is protected from electrical noise originating from the development PC.

    SWD Isolator

    The SWD Isolator can be connected between J-Link or Flasher and any Arm board that uses the standard 20-pin 0.1" male connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application (galvanic isolation). It is also useful to protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another typical field of application is the development of products with sensors or other analog circuitry, in which case the target hardware is protected from electrical noise originating from the development PC.

    USB Isolator

    The USB Isolator can be interconnected between J-Link or Flasher and the host PC. J-Link or Flasher are connected via USB to provide electrical isolation of the J-Link or Flasher from the host (PC) side. This is essential when development tools are not connected to the same ground as the application. It is also useful to protect the development tools from electrical spikes as overvoltage may occur when using low-budget USB hubs.
