54V 5kW power path protection reference design for AI data centers using TPS1689 and TPS1685 eFuses
TIDA-050090
概述
This reference design illustrates a 54V, 5kW input power path protection circuit for AI-powered data centers, utilizing one TPS1689 and five TPS1685 eFuse devices in parallel. These integrated high- current circuit protection devices provide multiple protections using a few external components, serving as a robust defense against overloads, short circuits, and excessive inrush current. The integrated PMBus® interface in the TPS1689 eFuse enables real-time monitoring, control, and configuration. Three devices are located on the top layer, three on the bottom layer.
特性
- Capable of carrying 100ARMS current at an elevated ambient temperature of 55°C without any external airflow
- Options to engage the enable power cycle and the quick output discharge (QOD)
- Control, telemetry, and configuration functionalities using PMBus through TPS1689 eFuse
- EEPROM to store the configuration file and the black box data after a fault
- Undervoltage, overvoltage, overcurrent, short- circuit, and overtemperature protections
