3 Description
The TPS25990x is an integrated, high-current circuit
protection and power management solution in a small
package. The device provides multiple protection
modes using very few external components and is a
robust defense against overloads, short circuits, and
excessive inrush current.
The integrated PMBus interface allows a host
controller to monitor, control and configure the system
in real-time. Key system parameters can be read
back for remote telemetry. Various protection, warning
thresholds and coefficients can be configured through
PMBus or stored in non-volatile configuration memory.
Blackbox fault recording feature helps in debug of
field failure/returns.
The device can be used as a standalone eFuse, or
connected as a primary controller in a parallel eFuse
configuration for higher current support. All devices
actively synchronize their operating state and share
current during start-up as well as steady state to avoid
over-stressing some of the devices which can result in
premature or partial shutdown of the parallel chain.
