The junction temperature at which the function is triggered, different for each IC, is set just below or above the Tj max.
This causes the junction temperature to rise and in this case, the band-gap voltage and internal offset voltages to decrease.
The thermocouple voltage reading is then compensated to reflect the reference junction temperature.
Thermal Shutdown(TSD): If the junction temperature rises above the specified limit, the thermal shutdown circuit turns the regulator off.
The junction temperature is the operating temperature of the PN junction of the semiconductor chip(wafer, die).
If the junction temperature exceeds the maximum junction temperature of +150°C, the device disables all channels.
The key to reduce junction temperature is to have a good radiator.
Thermal Warning Diagnostic If the junction temperature exceeds the programmed temperature limit, then a temperature fault is set immediately.
Thermal regulation reduces charge current when the junction temperature exceeds 110°C.
This article derives equations that use power dissipation and the ambient temperature to predict the junction temperature of a chip as a function of time.
Any error in reading the reference junction temperature will show up directly in the final thermocouple reading.
With led chip, and the LED are on large size PCB, the junction temperature on LED can be.
In this example, the power Pd and junction temperature Tj of the transistor are monitored.
Depending on the software parameterisation it is possible to limit the junction temperature by derating instantaneous power losses in real time.
This key factor, which characterizes the regulator, depends on load current and junction temperature of the pass transistor.
The key to prolonging its life is to reduce its junction temperature.
Therefore, the key to extending the life is to reduce the junction temperature.
The power supply IC used in the example here has an internal power transistor, and so the junction temperature of the power supply IC is measured.
So the key to prolonging life is to reduce junction temperature.
By knowing the thermal resistance of a package, one can calculate the IC's junction temperature for a given power dissipation and its reference temperature. .
