The MC33772BTA1AE from NXP Semiconductors is an integrated circuit designed for reliable and safe Li-ion cell control applications. This battery cell controller supports configurations from 3 to 6 cells and is suitable for high-voltage battery management systems up to 800 V, as well as 14 V Li-ion systems.
Key features include isolated 2 Mbps differential communication or 4 Mbps SPI interface, synchronized cell voltage and current measurements with a resolution of 113 µs, and fast data acquisition in 0.86 ms. The device operates within a V PWR range of 5.0 V to 30 V, with a 42 V transient for TPL communication. It also supports ISO 26262 functional safety up to ASIL D.
The MC33772BTA1AE is housed in a 48-pin LQFP package with an exposed pad, designed for surface mount installation. Its operating temperature range is -40°C to 125°C (TA). This IC is ideal for automotive and industrial applications such as energy storage systems (ESS), uninterruptible power supplies (UPS), and electric vehicles.
This solution addresses various battery management system topologies, including centralized and distributed daisy chain configurations, offering a robust alternative to CAN solutions. It integrates passive cell balancing with diagnostics and fault protection for over/under voltage conditions.
