TPS5402: BOOT UVLO

tateo yamashiro

Part Number: TPS5402

Hi,

We got a question from the customer about TPS5402.
Could you help us?

[Question]
How much is the variation of 2.1V BOOT UVLO? They want to make sure min and max value. They don't need guarantee. They will use it as reference.

Best Regards,

I don't find this date, and I think it doesn't impact customer to use this device.

Just keep the voltage of Boot cap more than 2.1V

Hi, Thank you for your reply. We got additional question. Does the IC have hysteresis of BOOT UVLO? They want to make sure the BOOT-LX rising voltage which the high side FET is turned ON.

Best Regards,
