DESCRIPTION
The TPS2475x provide highly integrated load
protection for 2.5 V to 18 V applications. The devices
integrate a hot swap controller and a power MOSFET
in a single package for small form factor applications.
These devices protect source, load and internal
MOSFET from 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 FET SOA protection ensures the
internal MOSFET operates within its safe operating
area (SOA) at all times and the load starts up at a
defined ramp rate. This enhances the internal
MOSFET performance while improving system
reliability. Power good, Fault, and current monitor
outputs are provided for system status monitoring and
downstream load control.
The devices are available in a 36-pin, 3.5 mm x 7
mm, QFN (RUV) package and fully specified over the
–40°C to 125°C operating junction temperature.
