8. Thermal Characteristics

The following table displays the thermal characteristics of various packages:

Table 13. Thermal Characteristics
		θa	θJc	θCa	θJa
			Junction to Case	Case to Ambient	Junction to Ambient Temperature
Package		Ambient Temperature
			Temperature	Temperature	θJc + θCa
		(°C)	(°C/W)	(°C/W)	(°C/W)
56	SSOP	70	24.4	23.3	47.7
100 TQFP		70	11.9	34.0	45.9
128 TQFP		70	15.5	27.7	43.2
56	QFN	70	10.6	14.6	25.2
56	VFBGA	70	30.9	27.7	58.6

The Junction Temperature θj, can be calculated using the following equation: θj = P*θJa + θa where,

P = Power

θJa = Junction to Ambient Temperature (θJc + θCa) θa = Ambient Temperature (70 C)

The Case Temperature θc, can be calculated using the following equation: θc = P*θCa + θa where,

P = Power

θCa = Case to Ambient Temperature θa = Ambient Temperature (70 C)

Note

15. Do not power IO with chip power off.
