About This Product

■Summary

The MP5990 is a fully integrated, compact PMBus compatible hot-swap protection device. It includes a hot-swap controller and a high-side power MOSFET (HS-FET) and can operate as a standalone device. The MP5990 can also operate as a hot-swap controller in parallel with the multiphase MP5991. The device can deliver up to 50A continuous output current (IOUT) per device at room temperature and up to 60A IOUT with airflow. The device limits backplane voltage drops by limiting inrush current to the load while a circuit card is inserted into a live backplane power supply. Current Limit (ILIMIT) Limits the internal MOSFET current (IFET) by controlling the gate voltage (VGATE) via the reference input and soft-start lamp. The MP5990 offers many features that simplify system design, including an integrated current mirror to monitor IOUT and integrated on-die temperature sensing. This eliminates the need for external current-sensing power resistors, power MOSFETs, and temperature-sensing devices. The MP5990 provides rich fault protection such as input voltage (VIN) overvoltage protection (OVP), IOUT overcurrent protection (OCP), short circuit protection (SCP), and overtemperature protection (OTP). The MP5990 detects short-circuit conditions on the gate, source, and drain of power MOSFETs. The fault status can be viewed in the fault report output (GOK). The MP5990 also features VIN undervoltage warning (UVW), output overcurrent warning (D_OC), and power good (PG) indication. The PMBus interface provides telemetry for input voltage (VIN), input current (IIN), input energy (EIN), and output voltage (VOUT), IOUT, input power (PIN), and output power (POUT). The MP5990 also monitors and reports fault status through the PMBus interface. The MP5990 is available in an LGA-45 (5mm x 7mm) package.
