Package Power Dissipation
(TJ max TA)/θJA
1
Maximum terminal current is bounded by the maximum current handling of
the switches, maximum power dissipation of the package, and maximum
applied voltage across any two of the A and W terminals at a given
resistance.
2
Maximum continuous current
3
Pulse duty factor.
4
Includes programming of 50-TP memory.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is defined by JEDEC specification JESD-51 and the value is
dependent on the test board and test environment.
