UCC5350-Q1: Minimum pulse width to respont

Hidekazu Someno

Part Number: UCC5350-Q1

Hello team,

My customer wants to know the following items about the input pulse at IN+ /IN- of UCC5250MC-Q1

- What is the minimum input pulse width that OUT has the response to it?

  (If you have any data or experiment result, It is useful.)

- In case the input pulse width is around 10-20ns,  Does OUT show the respond ? 

  (Customer is worry about OUT pin has unexpected response by noise pulse applied on IN pins.)

 Please support those questions.

 Best regards,

H.Someno

    Hi, Someno-san,

    We have a 10 ns deglitch filter on the logic inputs to block any spurious noise from falsely tripping the inputs (basically a LPF). 

    If the customer is worried about noise, they can also apply an external LPF as discussed in section 9.2.2.1 Designing IN+ and IN– Input Filter of the datasheet.

    Please mark this verified if I've anwered your question, Someno-san.
