XDP700002XUMA1

XDP700002XUMA1 is a hot-swap controller. This wide input voltage hot swap and system monitoring controller IC drives a single or multiple parallel N-Channel MOSFETs. In addition to a controlled turn ON, XDP700 provides continuous system health monitoring and communication to the main MCU via the PMBus interface. The high-speed communication through PMBus allows system designers to disable the downstream sub-systems fully or partially. It incorporates an extensive variety of system protections for safety operations and generates various protection responses depending on the severity of the incident. Latch off, reset, system shutdown and retry are some examples of response types. Its SOA protection effectively ensures that the system FET always operates under safe conditions. It is used in applications such as 48V pre-isolated DC/DC telecom infrastructure, -24V/-48V Industrial systems, power distribution systems, intelligent e-fuse, network router and switches.
