TPS2552: Reverse leakage current over temp

Kazuki Itoh

Part Number: TPS2552

Hi team,

Could you please provide me the reverse leakage current (I_REV) curve over temperature (-40 degC to +85degC) for TPS2552/3?

The datasheet only defines the data under Tj=25degC.

Hi Itoh-san,

Sorry, we also don't have this data.

Hi Kuno-san,

My customer’s target IREV is <3uA.

Could you make sure that the IREV doesn’t exceed 3uA over temperature?

Itoh

Hi Itoh-san,

Let me have a communication with our design team, maybe they will have some comment about this data.

Hi Itoh-san,

I have checked our electrical characterization data, the -6 sigma is 0.01 and +6sigma is 0.05 in the -40 degC, and -6 sigma is 0.08 and +6 sigma is 0.12 in 105 degC, so I guess our IREV will not exceed 3uA over temperature.

Best Regards,

Hi Kuno-san,

Hi,

Could you please clarify the unit?

Do you mean the -6 sigma is 0.01 uA and +6sigma is 0.05 uA in the -40 degC, and -6 sigma is 0.08 uA and +6 sigma is 0.12 uA in 105 degC?

Hi Itoh-san,

Sure, the unit is the uA.

Best, Regards,
