38.2 Absolute Maximum Ratings

Stresses beyond those listed in this section may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Table 38-1. Absolute Maximum Ratings
Symbol Description Conditions Min. Max. Unit
VDD Power Supply Voltage -0.5 6 V
IVDD Current into a VDD pin T=[-40, 85]°C - 200 mA
T=[85, 125]°C - 100 mA
IGND Current out of a GND pin T=[-40, 85]°C - 200 mA
T=[85, 125]°C - 100 mA
VRST RESET pin voltage with respect to GND -0.5 13 V
VPIN Pin voltage with respect to GND -0.5 VDD+0.5 V
IPIN I/O pin sink/source current -40 40 mA
Ic1(1) I/O pin injection current except RESET pin

Vpin<GND-0.6V or 5.5V<Vpin≤6.1V
4.9V<VDD≤5.5V

 -1 1 mA
Ic2(1) I/O pin injection current except RESET pin

Vpin<GND-0.6V or Vpin≤5.5V
VDD≤4.9V

 -15 15 mA
Ictot Sum of I/O pin injection current except RESET pin -45 45 mA
Tstorage Storage temperature -65 150 °C
Note:
    • If VPIN is lower than GND-0.6V, then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R = (GND-0.6V – Vpin)/ICn.
    • If VPIN is greater than VDD+0.6V, then a current limiting resistor is required. The positive DC injection current limiting resistor is calculated as R = (Vpin-(VDD+0.6))/ICn.
CAUTION: VRSTMAX = 13V

Care should be taken to avoid overshoot (overvoltage) when connecting the RESET pin to a 12 V source. Exposing the pin to a voltage above the rated absolute maximum can activate the pin’s ESD protection circuitry, which will remain activated until the voltage has been brought below approximately 10V. A 12V driver can keep the ESD protection in an activated state (if activated by an overvoltage condition) while driving currents through it, potentially causing permanent damage to the part.
