Exceeding the absolute maximum rating may damage the device. Note 2. The device is not guaranteed to function outside its operating rating. Note 3. I/O pin voltage is any external voltage to which an input or output is referenced. Note 4. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max); the junction-to-ambient thermal resistance, θJA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature. Note 5. Thermal resistance, θJA, applies to a part soldered on a printed circuit board. Note 6. Devices are ESD sensitive. Handling precautions recommended. Note 7. All limits guaranteed by testing on statistical analysis. Note 8. Continuous short circuit may exceed absolute maximum TJ under some conditions. Note 9. The MIC7221 requires 5kΩ pull-up resistor.
