TPS3808: Minimum VIT pin Hysteresis

Jejomar Ildefonso

Part Number: TPS3808
Other Parts Discussed in Thread: TPS3890,

Hi Team,

Do we have data on the VIT pin minimum hysteresis? This is for the G01 variant. Our customer needs this for proper determination of voltage limits within their power supply design. As far as I know hysteresis generally do not vary that much from the nominal value. Do we have data for a more defined minimum value?

Thanks in advance!


Kind Regards,

Jejomar

    Hi Jejomar,

    We do not specify minimum hysteresis for this device, and in general for a lot of our devices. In this case, as you can see by the variation of the maximum band, minimum hysteresis is "theoretically" zero. You're right in assuming that hysteresis does not usually vary much itself, it is rather a factor of the variation of the voltage level. Due to this, we also do not have characterization data on the subject. We do not guarantee any sort of minimum hysteresis for the TPS3808. We do spec it, however, on the similar TPS3890.

    Thanks,
    Abhinav.
