The TPS1689x 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. An integrated fast and accurate sense analog load current monitor facilitates predictive maintenance and advanced dynamic platform power management such as Intel PSYS and PROCHOT to optimize server and data-center performance. Blackbox fault recording feature helps in debug of field failure/returns. For higher current support, 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.
