The TPS24720 is an easy-to-use, full-featured protection device for 2.5-V to 18-V power
rails. This hot-swap controller drives an external N-channel MOSFET, while protecting source, load
and external MOSFET against multiple potentially damaging events. During startup, load current and
MOSFET power dissipation are limited to user-selected values. After startup, currents above the
user-selected limit will be allowed to flow until programmed timeout – except in extreme overload
events when load is immediately disconnected from source.
Programmable power limiting ensures the external MOSFET operates inside its safe
operating area (SOA) at all times. This allows use of smaller FETs while improving system
reliability. Power good, Fault, FET Fault, and current monitor outputs are provided for system
status monitoring and downstream load control.
