The TPS25990 is an integrated, high-current circuit protection and power management device 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 by 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 the debugging of field failures and 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 and steady state to avoid over-stressing some of the devices which can result in premature or partial shutdown of the parallel chain.
An integrated fast and accurate sense analog load current monitor facilitates predictive maintenance and advanced dynamic platform power management techniques such as Intel PSYS and PROCHOT to maximize system throughput and power supply usage. This in conjunction with an integrated digital oscilloscope function and Blackbox, helps with predictive maintenance in critical systems.
The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
