NXP Semiconductors has launched its new BMx7318/7518 household of 18-channel Li-ion battery cell controller built-in circuits, geared toward enhancing battery administration system (BMS) efficiency and security in electrical automobiles, industrial vitality storage programs and 48 V battery purposes. With a complicated structure that includes devoted Analog-to-Digital Converters (ADCs) per channel, the IC household affords versatile, pin-to-pin compatibility throughout gadget variants, offering a streamlined and cost-effective answer. It meets each Automotive Security Integrity Stage C (ASIL-C) and industrial Security Integrity Stage 2 (SIL-2) useful security certifications.
The BMx7318/7518 collection integrates analog front-end capabilities, battery junction field capabilities and gateway functionalities—together with current-sensing and Serial Peripheral Interface-to-Two-Wire Peripheral Hyperlink bridging—instantly onto the chip. In response to NXP, this integration reduces exterior part utilization by 50%, considerably reducing prices for unique gear producers and Tier 1 suppliers. The design delivers excessive electromagnetic interference immunity and sturdy bulk present injection resistance, supporting steady semi-centralized BMS configurations.
The brand new design emphasizes unbiased cell-sampling channels to stop crosstalk and enhance measurement accuracy. Its structure helps parallel balancing throughout all channels as much as 150 mA at ambient temperatures as much as 125°C, with single-channel functionality extending to 300 mA, significantly enhancing battery-balancing effectivity. It additionally options an ultra-low energy mode that consumes simply 5 µA, making it superb for extended storage or transportation eventualities. Moreover, a devoted {hardware} alarm pin is supplied for fast detection of overcurrent occasions.
“The BMx7318/7518 IC household represents one other step ahead in battery administration innovation,” stated Naomi Smit, Vice President and Common Supervisor, Driver and Vitality Methods at NXP Semiconductors. “By integrating superior ADC structure, high-current balancing, and sturdy EMI immunity, we allow our prospects to design extra environment friendly and scalable vitality programs. This answer reduces system complexity and meets the required security requirements for each automotive and industrial purposes. We’re proud to help the rising demand for sustainable vitality with know-how that delivers efficiency, flexibility, and reliability.”
The BMx7318/7518 household is predicted to turn into obtainable in November 2025.
