The maximum safety temperature, TS
, has the same value as the maximum junction temperature, TJ
, specified for the device. The IS
parameters represent the safety current and safety power, respectively. Do not exceed the maximum limits of IS
limits vary with the ambient temperature, TA
The junction-to-air thermal resistance, RθJA
, 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:
× P, where P is the power dissipated in the device.
, where TJ(max)
is the maximum junction temperature.
, where VDD1max
is the maximum high-side voltage and VDD2max
is the maximum low-side supply
