The MC33772B from NXP Semiconductors is an Automotive Qualified Lithium-ion Battery Cell Controller IC that has been designed for automotive applications such as hybrid electric vehicles (HEV), electric vehicles (EV) along with industrial applications such as energy storage systems, and uninterruptible power supply (UPS) systems. It requires an input voltage of 6 - 30 V. This BMIC consists of a microcontroller unit (MCU), digital interfaces, and a memory unit (EEPROM). It can manage 3-6 cells and conducts operations such as ADC conversions of differential cell voltages and currents, battery coulomb counting, and battery temperature measurements. This controller IC supports the SPI transformer physical layer interface to digitally transmit information for control and monitoring of the connected device.

The MC33772B  can detect internal and external fault conditions such as open lines, short-circuit, and leakages and includes under/over-voltage and temperature protection circuitries to prevent over-load-related damages. This AEC-Q100-qualified BMIC has an in-built diagnostic feature and supports ASIL D safety standards. It is available in a surface-mount package that measures 9 x 9 mm.
