Note 1: Design target only. Not 100% tested in production.

Note 2: Don’t use the TB7004FL after thermal shutdown is tripped, because the thermal shutdown circuitry operates

beyond the rated absolute maximum temperature. The thermal shutdown circuitry cannot always protect the

device from failure. The device may be permanently damaged before thermal shutdown is tripped, depending

on usage conditions. Refer to the description of thermal shutdown on page 13.
