NOTE
For applications which use the LVI, Freescale guarantee the functionality of
the device down to the LVI trip point (V_LVI) within the constraints outlined in
Chapter 9 Low-Voltage Inhibit (LVI) Module).

1. Power dissipation is a function of temperature.
2. K is a constant unique to the device. K can be determined from a known T_A and measured P_D. With this value of K, P_D and
T_J can be determined for any value of T_A.
