The RDA777T is the official MC33777 reference design. * The RDA777T2 integrates the MC33777A * The RDA777T3 integrates the MC33777B This reference design enables rapid prototyping of battery junction box (BJB) solutions for automotive and industrial applications. The MC33777 supports ASIL D - capable current measurement, high accuracy voltage measurement and pyrotechnic switch control, making it suitable for safety critical battery architectures. The RDA777T showcases a typical MC33777 system implementation designed to meet automotive constraints. Communication is implemented through an isolated daisy chain interface, simplifying integration into high-voltage battery systems.
