NOTES:
1. The power-on reset circuit resets the SMBus logic with VDD < VPOR and sets all I/Os to their default values.
2. The maximum total sink current must be limited to 54 mA at +85
°C, and 80 mA at +70 °C.
3. The maximum total source current must be limited to 54 mA at +85
°C, and 80 mA at +70 °C.
