BMx7318/7518 18-Channel Li-Ion Controller ICs

NXP Semiconductors BMx7318/7518 18-Channel Li-Ion Controller ICs monitor up to 18 battery cells and are designed for automotive high-voltage battery management systems (HVBMS), industrial energy storage systems (ESS), and 48V applications. These ICs are based on NXP's advanced architecture with dedicated analog-to-digital converters (ADC) per channel, offering flexible and diverse part number selection with pin-to-pin compatibility between the device derivatives. BMx7318/7518 ICs feature an integrated circuit design to achieve complete independence of the cell sampling channel, improve filtering accuracy, and avoid crosstalk. These systems have an ultra-low power mode of 5µA, meeting the needs of long-term storage and overseas transportation.
