    Digital isolator ISO7220C

    Hello, I use the ISO7220C digital isolator to separate my micro-controller part (F28335) from my power part (IGBT inverter). So isolators are used to propagate the PWM IGBT commands from the DSP to the inverter. My typical DC voltage is around 600V...

    RE: XDS100v2 crashes

    Not really, 24V input voltage. There are 5 DRV8432 motor drivers in my design driving .5Amps or so, switching currents may be higher... but the debugger is completely isolated by ISO7220C isolators (+ a 1Meg bleeding resistor connecting DebugGnd to...

    RE: TMDSHVMTRPFCKIT emulator connect error and ISO7220 operation.

    Jay, If you want to use the external XDS510USB, you'll need to change the ISO7220C isolater ICs that are included with the kit. We've noticed in the past that, for some reason, that 7220C transmission rate is too low for some of the faster...

    How can I evaluate the isolated voltage in application from the safty standard(VDE, CSA, UL)?

    • Resolved
    For example, in ISO7220C , I can find VDE, CSA, and UL information, and in VDE(IEC 60747-5-2), Basic
