Absolute Maximum Ratings

The maximum ratings are the limits to which the device can be subjected without permanently damaging the device. Note that the device is not guaranteed to operate properly beyond the maximum ratings. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.

(1) Guaranteed by design, not tested in production.

(2) All main power and ground pins should be connected to an external power source within the allowable range.

(3) VIN maximum value cannot exceed 5.5 V.

(4) It is recommended that VDD and VDDA are powered by the same source. The maximum difference between VDD and VDDA does not exceed 300 mV during power-up and operation.

Thermal Information

Thermal resistance is used to characterize the thermal performance of the package device, which is represented by the Greek letter "θ". For semiconductor devices, thermal resistance represents the steady-state temperature rise of the chip junction due to the heat dissipated on the chip surface.

θJA: Thermal resistance, junction-to-ambient.

θJB: Thermal resistance, junction-to-board.

θJC: Thermal resistance, junction-to-case.

ᴪJB: Thermal characterization parameter, junction-to-board.

ᴪJT: Thermal characterization parameter, junction-to-top center.

$Θ_mathsf{IA} = (mathsf{T}_mathsf{J} mathsf{·} mathsf{T}_mathsf{A}) mathsf{·} mathsf{P}_mathsf{D} tag{5-4}$

$Θ_mathsf{JB} equiv (mathsf{T}_mathsf{I} mathsf{T}_mathsf{B}) mathsf{P}_mathsf{D} tag{5-2}$

$Θ_mathsf{JC} equiv (mathsf{T}_mathsf{I} mathsf{T}_mathsf{C}) mathsf{P}_mathsf{D} tag{5-3}$

Where, T^J = Junction temperature.

T^A = Ambient temperature

T^B = Board temperature

T^C = Case temperature which is monitoring on package surface

P^D = Total power dissipation

θJA represents the resistance of the heat flows from the heating junction to ambient air. It is an indicator of package heat dissipation capability. Lower θJA can be considerate as better overall thermal performance. θJA is generally used to estimate junction temperature.

θJB is used to measure the heat flow resistance between the chip surface and the PCB board.

θJC represents the thermal resistance between the chip surface and the package top case. θJC is mainly used to estimate the heat dissipation of the system (using heat sink or other heat dissipation methods outside the device package).
