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 specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages, and is

based on a 4-layer standard JEDEC board.

MAXIMUM POWER DISSIPATION

The maximum power that the ADN8835 can dissipate is limited

by the associated rise in junction temperature. The maximum

safe junction temperature for a plastic encapsulated device is

determined by the glass transition temperature of the plastic,

approximately 125°C. Exceeding this limit may cause a shift in

parametric performance or device failure.

The driver stage of the ADN8835 is designed for maximum

load current capability. To ensure proper operation, it is

necessary to observe the corresponding maximum power

derating curves.
