TPS65983 OVP threshold corresponding to PDO setting

Hi,

My customer use PP_EXT path as PD source supporting 5/9/15/20V.  We need to know the "min typ max" value of OVP threshold corresponding to these 4 PDO setting.

Besides, is this related to OvpUsage and OvpTripPoint register setting in our chip?  Or these are two different OVP features?

Thanks!

Antony

  • Hi Antony,

    Regarding the OVP settings for PD source that support 4 different PDOs as you noted, we recommend that customer use OVPUsage settings in percentage. System Configuration Register (0x28) show OvpUsage settings, snippet from Firmware User's Guide below. For example if "10b" setting is used then OVP would trigger once VBUS voltage exceeds 10% of the negotiated PDO
