The NXP Semiconductors MC33771BTP1AE is a SMARTMOS lithium-ion battery cell controller IC. It is engineered for demanding automotive applications such as hybrid electric (HEV) and electric vehicles (EV), as well as industrial uses like energy storage systems (ESS) and uninterruptible power supply (UPS) systems.
This device performs ADC conversions for differential cell voltages and current, coulomb counting, and temperature measurements. Data is transmitted digitally via Serial Peripheral Interface (SPI) or Transformer Isolation (TPL) to a microcontroller. Key features include operation from 9.6 V to 63 V with 75 V transient, management of 7 to 14 cells, and isolated communication at 2.0 Mbps (TPL) or 4.0 Mbps (SPI).
It offers a maximum total voltage measurement error of 0.8 mV, synchronized cell voltage/current measurement with coulomb count, and total stack voltage measurement. The IC includes seven GPIO/temperature sensor inputs and a 5.0 V at 5.0 mA reference supply output. It supports automatic over/undervoltage and temperature detection, integrated sleep mode monitoring, and onboard 300 mA passive cell balancing with diagnostics.
The MC33771BTP1AE is designed to support ISO 26262 safety systems up to ASIL D and is qualified in compliance with AEC–Q100. It is housed in a 64-LQFP package and is suitable for surface mount applications.
