App note from Maxim Integrated on their power monitoring and supervisory ICs. Link here
It is inevitable to have a voltage protection circuit and a power monitoring circuit in any advanced electronics application such as Tablets, Smartphones and Notebooks etc. Power monitors are generally used in all applications that require to measure average power through the critical rails. These Supervisory ICs do not report faults in over-power scenarios. However, for portable applications , it is very important to report overpower/energy faults and assert an output to the microcontroller to prevent the damage of rest of the circuitry. A circuit, comprising of power monitor IC (MAX34417) and Supervisory IC (MAX16143) provides a solution to report under-voltage, over-voltage as well as over-power scenarios.
