TLV9021: Do you have any shift trend data of Pon parameter when ambient temperature is changed?

Kazuya Nakai59

Part Number: TLV9021


Tool/software:

Hello guys,

One of my customers is considering using TLV9021 for their next products.

At this moment, they have the following question.
Could you please give me your reply?

Q.
TLV9021 datasheet says that POWER ON TIME(Pon) is 20us as typical.
They would like to know how much the Pon time changes when the ambient temperature
changes to 85 degree C and -40 degree C. Do you have any data?

Your reply would be much appreciated.

Best regards,
Kazuya.

    Hi Kazuya-san,

    I apologize, but I can't share any data outside of what is present on the datasheet on the public forums.

    From what I see as a general trend, Pon goes up (takes longer to turn on) as temperature goes down.

    Is the POR functionality critical to your customer's system? We've recently discovered that the POR circuitry for this device is sensitive to the supply ramp rate; certain supply ramp rates seem to cause the POR circuitry to not function properly. If you can tell me more about your customer's requirements, I can suggest an alternate device that has POR without this supply ramp rate sensitivity.
