DESCRIPTION
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.
