(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, B, and W terminals at a given

resistance.

2 Maximum continuous current

3 Pulse duty factor.

4 Includes programming of OTP memory.

Data Sheet

Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

θJA is defined by JEDEC specification JESD-51 and the value is

dependent on the test board and test environment.
