The MP5981 is an integrated monolithic controller and switch with a high-side power MOSFET (HS-FET) and other circuitry that allows it to operate alone or be controlled via a hot-swap controller. The device can achieve up to 50A of continuous output current (IOUT) per device at room temperature, or up to 60A of continuous IOUT with air flow. The device limits the backplane voltage drop by limiting the inrush current to the load while a circuit card is inserted into a live backplane power source. It limits the internal MOSFET current by controlling the gate voltage via the current limit reference input and soft-start ramp. The MP5981 provides many features to simplify system design, such as an integrated current mirror to monitor IOUT and the die temperature. This eliminates the need for an external current-sense power resistor, power MOSFET, and thermal-sense device. The IC detects the power MOSFET’s gate, source, and drain short conditions. It also provides feedback to the hot-swap controller via the fault reporting output (GOK). The MP5981 can operate in parallel for high-current applications. All devices in parallel actively share current during soft start. The MP5981 is available in an LGA-32 (5mmx5mm) package.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP5981GLU is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MP5981GLU datasheet above.
Electronic component spot-market pricing for MP5981GLU fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MP5981GLU depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
