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 is detected, the device automatically shuts down the system in an orderly fashion. The device can sequence the supplies in any order at both power-up and power-down. The device has the ability to close-loop margin the power-supply output voltages up or down to a user-programmable level. The device contains an internal temperature sensor and can support up to four external remote temperature sensors. Once configured, the device can operate autonomously without any host intervention.
