Hi,

Can you please provide the following information for the TPS3828-33DBVT part?

1. Junction Temperature Max (Tj Max)

2. Thermal Resistance Junction to Ambient (Theta JA)

Thanks in Advance

Hi Dibin,

The TPS3828 is a low power supervisor with IDD typically 15uA and 400uA (max) current through the open drain RESET output. Because the power is so low, the junction temperature will practically be the ambient temperture. Therefore, the max Tj is +85 deg C.

Darwin

Hi Dibin,

For this older datsheet, it is found under the dissipation rating table on page 4 as operating factor. Theta JA would be the the inverse of 3.5mW / degC.
