High currents may be encountered during reverse battery, fortuitous open ground, and fortuitous open supply fault conditions. (2) See Application Information section for information on analog input voltage and ac coupling. THERMAL CHARACTERISTICS PARAMETER VALUE (Typical) UNIT Junction-to-case (heat slug) thermal RθJC 1 °C/W resistance, DKD package Junction-to-case (heat slug) thermal RθJC 1.2 °C/W resistance, PHD package This device is not intended to be used without a heatsink. Therefore, RθJA RθJA Junction-to-ambient thermal resistance °C/W is not specified. See the Thermal Information section. Exposed pad dimensions, DKD package 13.8 × 5.8 mm Exposed pad dimensions, PHD package 8 × 8 mm RECOMMENDED OPERATING CONDITIONS (1) MIN TYP MAX UNIT PVDDOP DC supply voltage range relative to GND 8 14.4 22 V PVDDI2C 6 14.4 26.5 V DC supply voltage range for I2C reporting (1) The Recommended Operating Conditions table specifies only that the device is functional in the given range.
