BQ2407x Thermal Consideration (cod. SLUS810k)

dtluigi
Intellectual 595 points

In the datasheet of the BQ2407x in the chapter about Thermal Consideration (par.12.3) it is reported the formula (pag.37):

P=(Vin-Vout)*Iout+(Vout-Vbat)*Ibat

but this formula is not corrected if the Functional Block Diagram (par.9.2) is the one reported at pag.14 with Q1 that shares both the output current that the charging current.

So the correct formula should be:

P=(Vin-Vout)*(Iout+Ibat)+(Vout-Vbat)*Ibat

Am I right?
