In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the
maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package
in the application (
θ
JA), as given by the following equation: TA(max)= TJ(max)–(θJA X PD(max)).

Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = [TJ(max) – TA] / θJA.
(2)
This thermal data is measured with high-K board (4 layers board according to JESD51-7 JEDEC standard).
over operating free-air temperature range, typical values are at TA = 25°C. Unless otherwise noted, specifications apply with
VI = 3.6 V, EN = VI, VSEL = VI, SYNC = GND, VSEL0[6] bit = 1.
