UCC27424-Q1: UVLO supported?

Genius 11915 points
Part Number: UCC27424-Q1
Other Parts Discussed in Thread: UCC27624, UCC27524, UCC27424

Hello Team,

according to https://www.ti.com/product/UCC27424-Q1 the IC supports UVLO, but this is not shown in the data sheet.

Can you explain this, please?

Thanks and Best Regards,

Hans

  • Hello Hans,

    It does seem that it is not specified in the datasheet. The part had a PSpice model so I tried finding the UVLO via that and got that it was roughly 3.8V rising and 3.6V falling, but that is definitely not a guarantee that the real part will function that way. 

    (red is VDD and green is the output.)

    I don't have any UCC27424 devices in my possession, so I cannot test it manually either. The UCC27524 or UCC27624 are alternatives that do have a clearly defined UVLO, but may be harder to acquire.

    thanks,

    Alex M.
