In a bold stride toward electrification and energy efficiency, NXP Semiconductors has introduced the BMx7318/7518 family—a cutting-edge lineup of 18-channel Li-ion battery cell controller ICs designed to revolutionize battery management systems (BMS) across electric vehicles (EVs), energy storage systems (ESS), and 48V applications.
Key Innovations
- Dedicated ADCs per channel: Each of the 18 channels features its own analog-to-digital converter, eliminating crosstalk and improving voltage measurement accuracy.
- Parallel cell balancing: All channels can balance simultaneously at 150mA, with single-channel capability reaching 300mA—even at ambient temperatures up to 125°C.
- Integrated architecture: Combines analog front-end, battery junction box, and gateway functions into a single chip, reducing external components by up to 50%.
- Ultra-low power mode: Consumes just 5µA, ideal for long-term storage and transport scenarios.
- Rapid fault detection: A dedicated hardware alarm pin ensures swift response to overcurrent events.
The BMx7318/7518 family meets automotive ASIL-C and industrial SIL-2 functional safety standards, making it a robust solution for mission-critical applications. Its electromagnetic interference (EMI) immunity and bulk current injection (BCI) resilience further enhance system stability.
As industries pivot toward scalable and sustainable energy solutions, battery management systems must deliver precision, reliability, and cost-efficiency. NXP’s new IC family addresses these demands by simplifying system design, improving performance, and lowering the bill of materials for OEMs and Tier 1 suppliers.
The BMx7318/7518 ICs are expected to hit the market in November 2025, with multiple variants offering flexible communication interfaces (SPI or TPL), GPIO configurations, and temperature ratings.icient energy technologies.
