Renesas' battery safety and protection portfolio covers a broad range of devices such as battery management controllers, charge system safety ICs and backup battery monitors and switches. We offer a dedicated single-package solution with an MCU and analog front-end (AFE) for battery management systems that constantly monitors the battery state. Our charging system safety circuits are optimized to provide a redundant safety protection to an Li-ion battery charging system by monitoring input voltage, battery voltage and charge current. Renesas also offers an automatic battery back-up switch, intended as a low-cost solution for the switching of systems between two power supplies: main and battery backup.
