(1) The maximum safety temperature, T
S, has the same value as the maximum junction temperature, T
J, specified for the device. The I
S and P
S parameters represent the safety current and safety power, respectively. Do not exceed the maximum limits of I
S and P
S. These limits vary with the ambient temperature, T
A.
The junction-to-air thermal resistance, R
θJA, in the
Thermal Information table is that of a device installed on a high-K test board for leaded surface-mount packages. Use these equations to calculate the value for each parameter:

J = T
A + R
θJA × P, where P is the power dissipated in the device.

max is the maximum high-side voltage and DVDD
max is the maximum controller-side supply voltage.
