MSP430I2020: MSP430i20xx series UL recognized?

Part Number: MSP430I2020


Team,

Are any of the MSP430i20xx family devices UL recognized?

Asking on behalf of a customer.

Thanks,

/ Wolfgang

    Generally, if you don't plug into the wall, it does not need UL certification

    Hello Wolfgang,

    As Keith indicated, UL Certification is a system level certification. We currently do not have any system level reference designs utilizing this part that have gone through such certification.

    Hi Keith, Jace,

    Thank you for prompt replies. My customer develops EV chargers which will require end product certification toward regional standards, like UL Certification.

    Customer is wondering if the component MSP430 is UL Recognized which as I understand is a sub-level "certification" of a component used in e.g. electric power delivery equipment such as e-meters, or high power chargers.

    From https://forum.digikey.com/t/understanding-ul-when-is-it-applicable/7223 :

    Components That May Have UL Recognized Certification

    Here is an incomplete list of common components that could have UL Recognized documentation:

    • Single and Multi-Conductor Cable: Certain jacket materials tend to be flammable, UL 94 often applies in this case.
    • Class-X and Class-Y Saftey Capacitors: These types of capacitors have such a high voltage rating that fire danger or electrical shock (sparking) is possible if used incorrectly or fail.
    • Some Batteries: batteries are often found in household electronics, so UL Recognition may apply.
    • Heat Shrink or Other Cable Protection
    • Fuses
    • Circuit Breakers
    • Anything That is Specifically Designed for Circuit Protection: some examples may include gas discharge tubes, inrush current limiters, surge suppression IC's, and TVS components.
    • Certain Power Management IC's

    The general rule is that anything built for high standards or providing power typically tend to have UL Recognized Certification.

    With MSP430i20xx being a high precision power measurement component that could be used as part of the EV charger power output regulation circuit, this might qualify for UL Recognition? Or does this apply only to the power delivery components, i.e. FETs, drivers, etc?

    Thanks,

    / Wolfgang

    Hello Wolfgang,

    Such a certification would of been done by our end customers, as such we don't have a direct claim to any type of UL certification or recognition. It is not something we have pursed for an individual part. My take from your highlight though, that this would be IC's specific to power management, not necessarily an MCU for power measurement/monitoring.

    I can say that MSP430s are used  in the EV Charging end equipment in various roles.

    Hi Jace,

    Okay, understood. I'll take your feedback to my customer and this should close this request.

    Thanks again,

    / Wolfgang
