DESCRIPTION (continued)

They also provide single-line fault reporting, electrical isolation of faulty cards, and protection against nuisance

overcurrent trips. The TPS2398 latches off in response to current faults, while the TPS2399 periodically retries

the load in the event of a fault.

NOTES 1: Stresses beyond those listed under ”absolute maximum ratings” may cause permanent damage to the device. These are stress ratings

only and functional operation of the device at these or any other conditions beyond those indicated under ”recommended operating

conditions” is not implied. Exposure to absolute−maximum−rated conditions for extended periods may affect device reliability.

2: All voltages are with respect to −VIN (unless otherwise noted).

3: With 100-k

Ω minimum input series resistance, −0.3 V to 15 V with low impedance.

4: With 10-k

Ω minimum series resistance, −0.3 V to 80 V with low impedance.
