These power management ICs are used to manage the activation of the power supplies of key components and sub-systems in a computer system, including CPU, DRAM, Graphics, High Speed I/O and USB, according to the ACPI specification. In addition, under-voltage condition (indicating fault on the supply line) is monitored and the main power supply (e.g. ATX) is shut-down to prevent damage to the system. A soft-start feature reduces stress on power supply components and increases product reliability.
