TPS1689x 20A Stackable eFuse

Texas Instruments TPS1689x 20A Stackable eFuse is an integrated high-current power management and circuit protection solution in a small package. The device uses very few external components to provide multiple protection modes and is a robust defense against short circuits, overloads, and excessive inrush current. The integrated PMBus interface enables a host controller to control, monitor, and configure the system in real time. Key system parameters can be read back for remote telemetry. Various coefficients and protection/warning thresholds can be stored in non-volatile configuration memory or configured through PMBus. An integrated, accurate, and fast sense-analog load-current monitor enables advanced dynamic platform power management and predictive maintenance, such as Intel PSYS and PROCHOT, to optimize server and datacenter performance. The Blackbox fault recording feature helps debug field failures/returns. For higher current support, Texas Instruments TPS1689x can be connected in parallel with TPS1685x. The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
