XDP710002XUMA1

XDP710002XUMA1 is a wide input voltage hot swap and system monitoring controller IC that drives a single or multiple parallel N-Channel MOSFETs. In addition to a controlled turn ON, it 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.
