MAXIM INTEGRATED PRODUCTS  MAX34461ETM+  电压监控器, 3V-3.6V电源, 2.048V阈值/170 ms延迟, 高电平有效, 低电平有效, TQFN-48

The is a PMBus 16-channel voltage monitor and sequencer in 48 pin TQFN package. It 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. The 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. 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. Typical applications include network switches/routers, base stations, servers and smart grid network systems.
