MC33772BTP2AE

Overview

The MC33772BTP2AE is a six-channel lithium-ion battery cell controller IC manufactured by NXP Semiconductors. It operates within an automotive-grade temperature range of -40°C to +125°C and utilizes an LQFP-48 surface-mount package. The device supports SPI communication for interaction with microcontrollers and is designed for high-voltage battery management systems. It provides precise voltage, current, and temperature measurements across six channels, featuring redundant measurement capabilities to ensure functional safety compliance.

Feature Summary

• Six-channel architecture for comprehensive lithium-ion cell monitoring
• Redundant measurement branches for enhanced diagnostic accuracy
• Integrated decision engine for autonomous fault detection and reaction triggering
• Supports isolated daisy-chain or serial peripheral interface communication

Applications

• High-voltage battery management systems in electric vehicles
• Hybrid electric vehicle powertrain control units
• Industrial energy storage system monitoring
• Automotive battery junction box applications

Procurement Notes

Verify the specific suffix 'TP' against official NXP documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for LQFP-48 packages. Confirm that the AEC-Q100 qualification status meets project requirements for automotive deployment. Cross-reference ordering information directly with manufacturer datasheets to avoid substitution errors.

Selection Notes

Select this component when a six-channel solution with redundant measurement paths is required for ASIL D compliant designs. Consider the integrated decision engine for reducing microcontroller load during fault events. Evaluate the SPI interface speed and isolation requirements against system topology constraints. Compare channel count and precision against larger variants like the MC33772C series if more cells need monitoring.
