(2) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDEC- standard test exists, but a close description can be found in the ANSI SEMI standard G30-88. (3) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8. 5.12 Thermal Resistance Characteristics PARAMETERS VALUE UNIT RθJA Junction-to-ambient thermal resistance, still air(1) QFN 24 pin (RLL) 38.7 ºC/W TSSOP 16 pin (PW16) 106.5 RθJC Junction-to-case (top) thermal resistance(2) QFN 24 pin (RLL) 39.5 ºC/W TSSOP 16 pin (PW16) 41.2 RθJB Junction-to-board thermal resistance(3) QFN 24 pin (RLL) 8.6 ºC/W TSSOP 16 pin (PW16) 51.5 5.13 Timing and Switching Characteristics 5.13.1 Power Supply Sequencing Figure 5-5 shows the power cycle, SVS, and BOR reset conditions. Figure 5-5. Power Cycle, SVS, and BOR Reset Conditions Table 5-1 lists the characteristics of the SVS and BOR. (1) A safe BOR can only be correctly generated only if DVCC must drop below this voltage before it rises. (2) When an BOR occurs, a safe BOR can be correctly generated only if DVCC is kept low longer than this period before it reaches VSVSH+. Table 5-1.
