PRODUCTION DATA.
The DC current under maximum load power condition will be around 7.03 A. Power dissipation in the switch is calculated in Equation 3. RON is assumed to be 20 mΩ because this is the maximum specification. In practice, RON will be lower.
The junction temperature of the device can be calculated using Equation 5 and the RθJA value from the Specifications section.
The maximum junction temperature rating for device is TJ = 150°C. Based on the above example calculation, the device temperature will stay below the maximum rating.
