Datasheet

Description

The MP5514 is an input power conditioning power management IC (PMIC) designed for enterprise solid-state drives (SSDs), non-volatile dual-inline memory modules (NVDIMMs), and other backup system applications. The device features input current limiting and reverse current blocking. It also integrates an MPS-patented, high-efficiency, bidirectional buck-boost converter with a single inductor for energy storage and system power backup during an input power failure.

The MP5514 also provides an I²C interface and analog-to-digital converter (ADC). Users can set the input current limit (I_{IN_LIMIT}) and slew rate, and can perform capacitor health tests via the I²C. The MP5514 monitors system statuses, such as the input voltage (V_IN), input current (I_IN), storage voltage (V_STRG), and temperature. It also provides interrupt options for these features.

Internal input current blocking prevents inrush current during start-up, and reverse current blocking prevents backup energy from flowing to the failing VIN port. MPS’s patented energy storage and release management control circuit minimizes the storage capacitor (C_STRG) requirement. The circuit increases V_IN to provide a higher V_STRG to store energy. If an input outage occurs, this energy is released to the system during a hold time (t_HOLD).

The MP5514 requires a minimal number of standard external components, and is available in a QFN-30 (5mmx5mm) package.
