MAX34451 - Maxim Integrated

MAX34451 PMBus 16-Channel V/I Monitor and 12-Channel Sequencer/Marginer

The MAX34451 is a power-supply system manager that is capable of monitoring up to 16 different voltage rails or currents and is also capable of sequencing and margining up to 12 power supplies. The system manager monitors the power-supply output voltages and currents and constantly checks them for user programmable over and under threshold limits. If a fault.
