The MC33777, which will be presented for the first time at electronica 2024, is a battery junction box chip from NXP Semiconductors that combines all the essential functions of a battery management system (BMS) in a single device. It protects high-voltage batteries from overcurrent by continuously monitoring the battery current and current slew rate every eight microseconds. It detects and responds to a variety of configurable events up to ten times faster than conventional ICs, without having to wait for certain current thresholds to be exceeded. The MC33777’s fuse emulation technology also makes it possible to remove expensive and unreliable fuses from the system, resulting in significant cost savings for OEMs and Tier 1 suppliers. In addition to the MC33777, NXP’s portfolio also includes battery cell controllers, battery gateway ICs, production-ready software and safety documentation. (oe)
