Product Overview
MC33772CTC1AE is a battery cell controller IC. The MC33772C is a SMARTMOS lithium-ion battery cell controller IC designed for automotive applications, such as hybrid electric (HEV) and electric vehicles (EV) along with industrial applications, such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The device performs ADC conversions of the differential cell voltages and current, as well as battery coulomb counting and battery temperature measurements. The information is transmitted to MCU using one of the microcontroller interfaces: serial peripheral interface (SPI) or isolated daisy chain communication interface [also referred as transformer physical layer (TPL)] which supports both capacitive and inductive isolation between nodes of the IC. Applications include automotive: 12V and high-voltage battery packs, E-bikes, e-scooters, drones, energy storage systems, uninterruptible power supply (UPS), battery junction box.
