The MC33772BSA1AE from NXP Semiconductors is an integrated circuit designed for battery cell control in Lithium-Ion applications. It supports battery configurations from 3 to 6 cells and operates within a power supply voltage range of 5.0V to 30V, with transient capability up to 42V for TPL communication.
This device features isolated 2 Mbps differential communication or 4 Mbps SPI interface for robust data transfer. It enables synchronized cell voltage and current measurements with a typical acquisition time of 113 µs for cell voltages and current, and 0.86 ms for full pack data acquisition. The controller also includes onboard passive cell balancing with diagnostics.
Packaged in a 48-lead LQFP exposed pad, the MC33772BSA1AE is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TA), making it suitable for demanding automotive and industrial environments. The device is designed for high-voltage battery management systems (200V–800V) and 14V Li-ion battery management systems, as well as energy storage systems and uninterruptible power supplies.
Key features include support for ISO 26262 functional safety up to ASIL D, fault protection for over/under voltage conditions, and seven ADC/GPIO/temperature sensor inputs. This makes the MC33772BSA1AE a reliable solution for mission-critical battery monitoring.
