Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
I/O pin voltage is any external voltage to which an input or output is referenced.
The maximum allowable power dissipation is a function of the maximum junction temperature, T_J(max); the junction-to-ambient thermal
resistance, θ_JA; and the ambient temperature, T_A. The maximum allowable power dissipation at any ambient temperature is calculated using
P_D(max) = (T_J(max) – T_A) ÷ θ_JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
Thermal resistance, θ_JA, applies to a part soldered on a printed circuit board.
Devices are ESD sensitive. Handling precautions recommended.
All limits guaranteed by testing on statistical analysis.
Continuous short circuit may exceed absolute maximum T_J under some conditions.
The MIC7221 requires 5kΩ pull-up resistor.
