3 Description

The TPS24710/11/12/13 is an easy-to-use, 2.5 V to

18 V, hot-swap controller that safely drives an

external N-channel MOSFET. The programmable

current limit and fault time protect the supply and load

from excessive current at startup. After startup,

currents above the user-selected limit will be allowed

to flow until programmed timeout – except in extreme

overload events when the load is immediately

disconnected from source. The low, 25mV current

sense threshold is highly accurate and allows use of

smaller, more efficient sense resistors yielding lower

power loss and smaller footprint.

Programmable power limiting ensures the external

MOSFET operates inside its safe operating area

(SOA) at all times. This allows the use of smaller

MOSFETS while improving system reliability. Power

good and fault outputs are provided for status

monitoring and downstream load control.
