UCC5310: difference between UCC53xx and ISO58/54xx

Part Number: UCC5310
Other Parts Discussed in Thread: UCC21520

Hi, I wonder what's the difference between UCC53XX and ISO58/54xx isolated gate driver?

I have some digital power customer making large AC/DC and DC/DC power module, and isolated MOSFET gate driver should be used. Should I promote UCC or ISO series products?

In ESP it's said that UCC is suitable for MOSFET and ISO is suitable for IGBT, is it correct?

    Hi Howard,

    Thanks for the question.

    There are a few differences between the ISO58/54xx and the UCC53xx families, however both can drive MOSFET and IGBT. Some of the primary differences are listed below:

    • UCC53xx 'D' package is our 3kV isolation, ISO54/58xx have higher isolation rating for reinforced isolation.
    • UCC53xx has a lower pin count, and has a few variants to support either a miller clamp, split outputs, or supply UVLO
    • ISO54/58xx has a higher pinout and includes a miller clamp, a DESAT function (for IGBT) and an option for split outputs
    • ISO54/58xx includes RDY, /FLT, and RST pins for more control/monitoring from the MCU

    Regarding which to promote, it depends on whether or not the customer needs reinforced isolation, and if they want the DESAT and digital IO functions. Also if they want a dual channel isolated driver you can also look at the UCC21520.

    Take a look at the product page as well, which has our entire isolated gate driver portfolio and a compare function. http://www.ti.com/lsds/ti/isolation/isolated-gate-driver-products.page
