MC33772CTC1AER2

Overview

The MC33772CTC1AER2 is a six-channel lithium-ion battery cell controller IC manufactured by NXP Semiconductors. Designed for automotive and industrial applications, it manages 3 to 6 cells in high-voltage battery systems. The device features integrated passive balancing with 300 mA MOSFETs, synchronous current measurement with ±0.5% accuracy, and a built-in Coulomb counter. It supports ISO 26262 ASIL D functional safety and operates within a voltage range of 6V to 30V. Communication is facilitated via isolated daisy-chain or SPI interfaces.

Feature Summary

• Integrated passive cell balancing with diagnostic capabilities
• Synchronous current measurement with high precision
• Support for isolated daisy-chain and SPI communication protocols
• Built-in Coulomb counter for state-of-charge monitoring

Applications

• Hybrid electric vehicle (HEV) battery management systems
• Electric vehicle (EV) high-voltage battery packs
• Energy storage systems (ESS)
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix TC1 against official NXP documentation to confirm pinout and feature configuration. Ensure compatibility with the target system's communication protocol requirements. Check RoHS compliance status and moisture sensitivity level before integration. Confirm availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring ASIL D functional safety certification. It is suitable for systems needing precise current sensing and cell balancing without external balancer ICs. Consider the 48-HLQFP package constraints during PCB layout. Evaluate the need for isolated communication if operating in high-voltage environments.
