Analog Devices / Maxim Integrated MAX20751 PMBus Multiphase Master IC
Der Maxim Integrated MAX20751 PMBus™ Multiphasen-Master-IC kann bis zu vier Smart-Slave integrierte Leistungsgeräte betreiben. Bei Verwendung der Maxims Smart-Slave-ICs bietet das Gerät eine hochdichte und flexible Lösung, die auf eine Reihe von in Kommunikationsgeräten verwendeten Leistungslasten zugeschnitten werden können.
The device incorporates current reporting, temperature monitoring, fault detection, and PMBus support. The individual smart slaves detect overcurrent and overtemperature faults and faults communicated through the master IC. The highest junction temperature is reported both before and after smart-slave regulation.
The device features an integrated switching regulator that can optionally supply the VDD rail for the master controller and smart-slave devices to reduce the power-rail requirements and simplify the regulator design.
