NXP Semiconductors has launched the new BMx7318/7518 family of 18-channel Li-ion battery cell controller ICs to enhance battery management systems in electric vehicles, energy storage systems, and 48 V battery applications.
The IC family features dedicated ADCs per channel, offering flexibility, pin-to-pin compatibility, ASIL-C, and SIL-2 safety certifications, reducing costs for manufacturers.
The design focuses on independent cell-sampling channels, parallel balancing up to 150 mA, ultra-low power mode, and a hardware alarm pin for overcurrent event detection.
The BMx7318/7518 family provides advanced ADC architecture, high-current balancing, and robust EMI immunity, expected to be available in November 2025.
