AMC Power Module Management

Reference Design LogoThis reference design describes the use of a Lattice Power Manager II device as a Payload Power Management Coprocessor in an Advanced Mezzanine Card (AMC) system. The Advanced Mezzanine Card is intended to be plugged into a carrier system, either a card or a shelf, and supports the hot swapping of the Mezzanine card in the carrier system without affecting the operation of the host carrier system.

Features

  • 12V hot swap controller
    • Operate MOSFETs in Safe Area of Operation (SOA)
    • Provide over-current and short-circuit protection
    • Programmable SOA and over-current levels
  • Six supply monitors
    • 3.3V I/O, 2.5V, 1.8V, and 1.2V monitors
    • Two unassigned VMON inputs available to the user
  • CPU reset
  • Power fault output
  • I2C interface between the MMC and the Power Manager II
