UCC27211A-Q1: Rise Time

Part Number: UCC27211A-Q1

Hello Team,

My customer would like to know the correct rise time for  UCC27211A-Q1? The Product page and part finder show different values compare to the datasheet.

 Also just want to make sure if they can drop this part into a design with a UCC27212A and have a performance increase along with a reliability increase from the better UVLO to justify the increased expense.



  • Hello Renan,

    For IC parameters such as rise time, the datasheet parameter table has the correct values and has been reviewed and validated before releasing the devices.

    The UCC27211A-Q1 and UCC27212A are very similar IC with the UCC27212A having a lower UVLO thresholds. Make sure that the application is compatible with the UCC27211A-Q1 recommended operating UVLO range, then replacing the UCC27212A with the UCC27211A-Q1 will have no issues.

    Regarding reliability differences, the UCC27211A-Q1 has been specifically qualified as an automotive device which as more reliability testing than the UCC27212A which is a commercial device.
