6 / 12 page 6 Thermal Resistance vs. Mounting Pad Area The maximum rated junction temperature, TJM, and the thermal resistance of the heat dissipating path determines the maximum allowable device power dissipation, PDM, in an application. Therefore the application’s ambient temperature, TA ( oC), and thermal resistance RθJA (oC/W) must be reviewed to ensure that TJM is never exceeded. Equation 1 mathematically represents the relationship and serves as the basis for establishing the rating of the part. In using surface mount devices such as the TSOP-6 package, the environment in which it is applied will have a significant influence on the part’s current and maximum power dissipation ratings. Precise determination of PDM is complex and influenced by many factors: 1. Mounting pad area onto which the device is attached and whether there is copper on one side or both sides of the board. 2. The number of copper layers and the thickness of the board. 3. The use of external heat sinks. 4. The use of thermal vias. 5. Air flow and board orientation. 6. For non steady state applications, the pulse width, the duty cycle and the transient thermal response of the part, the board and the environment they are in. Intersil provides thermal information to assist the designer’s preliminary application evaluation. Figure 20 defines the Test Circuits and Waveforms FIGURE 16. GATE CHARGE TEST CIRCUIT FIGURE 17.
