Platform Manager 2 & L-ASC10

Manage power, thermal & control planes in real time

Reduced time to market – Fast and reliable fault detection/logging for power & thermal management and board control logic, coupled with simulation and in-system debug support.

Simple, scalable, end-to-end – Scalable platform for voltage, temperature, logic and I/O that can be easily expanded using L-ASC10 chips with glue-less interfaces.

Reduce BOM and cost – Designs across a wide range of systems can standardize on the Platform Manager 2 family instead of multiple single function ICs from multiple vendors.

Features

  • Full fault coverage – monitor all rails and temperature nodes
  • Manage from 10 to 80 supplies using just the required number of L-ASC10 hardware management expanders
  • Minimize fault propagation by enabling individual hardware management sub-blocks (power, thermal & control path) to respond to faults in other blocks within nano-seconds
  • Save CPLD I/O pins by eliminating the need to monitor power-good signals of DC-DC converters
  • Reliable power & thermal fault detection in hardware, as opposed to software routines
