MAX34461AA01+

MAX34461AA01+ is a system monitor that is capable of managing up to 16 power supplies. The power-supply manager monitors the power-supply output voltages and constantly checks for user-programmable overvoltage and undervoltage thresholds. If a fault is detected, the device automatically shuts down the system in an orderly fashion. This device can sequence the supplies in any order at both power-up and power-down. With the addition of external current DACs, the device has the ability to close-loop margin the power-supply output voltages up or down to a user-programmable level. This 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. Applications include network switches/routers, base stations, servers, and smart grid network systems.

• 16 channels of power-supply management, 3.0V to 3.6V supply voltage
• On-board non-volatile black box fault logging and default configuration setting
• Time- and event-based sequencing, programmable up and down sequencing
• PMBus-compatible command interface, easy-to-use GUI
• Flexible measurement and monitoring capability, automatic closed-loop margining improves accuracy
• Remote ground sensing improves measurement accuracy
• Up to 16 GPOs, no external clocking minimizes system-level design
• I²C/SMBus-compatible serial bus with bus timeout function
• Power-supply voltage measurement and monitoring
• Operating temperature range from -40°C to +85°C, 48-lead TQFN-EP package
