Fully Integrated Hot-Swap Solution: MP5990

Integrated, Simplified Hot-Swap Solution Reduces Board Space

The MP5990 is the industry’s first fully integrated, 16V, 50A hot-swap solution with a PMBus interface. It is optimized for applications where protection against hot-plug functions is critical, including servers, PCIe cards, and 5G telecom and networking. The MP5990 integrates a hot-swap controller and power MOSFET with current and temperature sensing, plus an I2C/PMBus interface and a non-volatile memory (NVM). This flexible solution offers the industry’s best ±1% IMON reporting accuracy and excellent thermal performance.
