MP5515 - Power Back-Up Manager

General Description

The MP5515 is an input power conditioning PMIC targeting enterprise solid-state drives, NVDIMM, and other applications with back-up system requirements.

Key Features

  • The internal input current-limit block prevents inrush current during system start-up while the reverse-current block prevents backup energy from flowing to the failing VIN port. MPS’s patented energy storage and release management control circuit minimizes the storage capacitor requirement. It pumps the input voltage to a higher backup voltage and releases the energy over a hold-up time to the system bus voltage in case of an input outage. The MP5515 requires a minimal number of standard, exte.

MP5515 Wide Input 2.7 - 18V, 5A, High-Efficiency Bidirectional, Power Back-Up Manager with Integrated Hot-Swap, I2C, ADC, and Cap Health Test DESCRIPTION The MP5515 is an input power conditioning PMIC targeting enterprise solid-state drives, NVDIMM, and other applications with back-up system requirements. The MP5515 consists of input current limiting, input reverse current blocking, and an MPS-patented, high-efficiency, bidirectional, boost-buck converter with only one inductor for energy storage and system back-up power when there is an input power failure. The MP5515 also provides I2C interface and ADC. By using the I2C, users can set the input current limit, slew rate, and perform cap health tests.
