Analog Devices Inc. MAX34461A PMBus Voltage Monitor & Sequencer

Analog Devices Inc. MAX34461A PMBus Voltage Monitor and Sequencer is designed for up to 16x power supplies and monitors voltages and checks against user-set overvoltage and undervoltage limits. Upon detecting a fault, the device shuts down the system and can sequence supply operations during startup and shutdown. With external current DACs, the Analog Devices MAX34461A can adjust supply voltages to user-set levels. The series includes an internal temperature sensor and supports up to four external remote sensors. Once configured, the module operates autonomously without needing host intervention.
