NXP Semiconductors MC33774A Li-Ion Battery Controller ICs include an independent internal architecture that achieves ASIL D functional safety targets at cell voltage and temperature measurements. These ICs support busbar monitoring with an input voltage as low as -3V. The MC33774A 18-channel ICs are qualified for less than 1.5 mV of voltage measurement error over the full temperature and cell voltage range. These ICs control passive cell balancing with up to 360mA current per channel and up to 125°C ambient temperature. The MC33774A 18-channel ICs allow maximizing asset utilization (such as ESS and EV Fleet) via fast real-time balancing.
