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.
