Monolithic Power Systems (MPS) MP5990 Fully Integrated Hot-Swap Solutions

Monolithic Power Systems (MPS) MP5990 Fully Integrated Hot-Swap Solutions consist of a hot-swap controller and a High-Side power MOSFET (HS-FET), which operate as a standalone device. These devices achieve up to 50A of continuous output current (IOUT) per device at room temperature and up to 60A of continuous IOUT with airflow. The MP5990 hot-swap solutions limit the backplane voltage drop by limiting the inrush current to the load. These devices feature an integrated current mirror to monitor IOUT and integrated on-die temperature-sensing. The MP5990 hot-swap solutions detect power MOSFET gate, source, and drain short conditions.

The MP5990 hot-swap solutions provide rich fault protections such as Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP). These hot-swap solutions feature Under-Voltage Warning (UVW), output over-current warning (D_OC), and Power Good (PG) indications. The MP5990 hot-swap solutions monitor and report fault statuses through the PMBus interface. These hot-swap solutions are available in an LGA-45 (5mm x 7mm) package. Typical applications include hot swaps, PC cards, disk drives, servers 5G telecom, networking, and laptops.
