applications. The device performs ADC conversion on the differential cell voltages and

currents. It is also capable of battery charge coulomb counting and battery temperature

measurements. The FRDM33772BSPIEVB is an ideal platform for rapid prototyping of

MC33772B-based applications that involve current, voltage, and temperature sensing.

The FRDM33772BSPIEVB supports standard SPI interface. The information is digitally

transmitted to a microcontroller for processing.
