UCC27531-Q1: UCC27531-Q1 replace

Part Number: UCC27531-Q1
Other Parts Discussed in Thread: UCC27531, TDC1000

I am currently powering VDD at 30V and everything works well, input max is 5v 

I want to look for a new IC which has similar function/footprint as this UCC27531 but has higher voltage VDD input. (around 45 - 50v)

    Hello,

    We do not currently have a low side driver with VDD range beyond 35V in our portfolio.

    Most gate drive topologies will typically not require gate drive voltage beyond 25V-28V in the case of the SiC or IGBTs assuming bipolar supply for negative turn-off.

    Hi Mamadou, 

    Thank you very much for answering. 

    The current design with UCC27531 is

    VDD - 30V 

    IN - TX signal from TDC1000, 665Khz (peak is 5v)

    EN is connected to IN 

    OUTH is connected to a ultrasonic transmitter (tx pin) 

    So basically it 'pull up' the signal voltage peak to 30v now

    May i know if have any other amplifier IC can achieve this , with this frequency? 

    Thank you for your help!

    Hello,

    Keep in mind our drivers are typically intended to drive capacitive loads such as MOSFETs.

    You may check with the amplifier team by posting a separate thread with details of applications.

    Meanwhile, I will mark this thread as "resolved".

    But please let us know if you have additional gate drivers questions.

    Thanks.
