The MC33771BTP2AE from NXP Semiconductors is a SMARTMOS lithium-ion battery cell controller IC. It is designed for demanding automotive applications like hybrid electric (HEV) and electric vehicles (EV), as well as industrial uses such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems.
This device performs ADC conversions for differential cell voltages and current, along with battery coulomb counting and temperature measurements. The 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 (75 V transient), management of 7 to 14 cells, and a voltage measurement error of only 0.8 mV maximum.
The MC33771BTP2AE supports isolated 2.0 Mbps differential communication or 4.0 Mbps SPI. It offers synchronized cell voltage/current measurement with coulomb count, total stack voltage measurement, and seven GPIO/temperature sensor inputs. The IC includes onboard 300 mA passive cell balancing with diagnostics, hot-plug capability, and detection of internal and external faults. It is designed to support ISO 26262 up to ASIL D safety systems and is qualified in compliance with AEC-Q100.
Packaged in a 64-LQFP Exposed Pad, the MC33771BTP2AE is suitable for surface mount applications. Its operating temperature range is -40°C to 105°C (TA).
