MC33772BTB1AER2

Overview

The MC33772BTB1AER2 is a battery cell controller IC from NXP Semiconductors designed for lithium-ion battery management. It features six voltage measurement channels and supports isolated TPL communication. The device operates within a supply voltage range of 5 V to 30 V, with transient tolerance up to 42 V in SPI mode. It is housed in an LQFP-48 package and supports surface mount installation. The component includes onboard passive balancing capabilities and integrated diagnostic functions.

Feature Summary

Supports isolated TPL communication for efficient data transfer between the battery controller and microcontroller.
Provides advanced voltage and temperature measurement with high precision across multiple channels.
Integrates onboard passive balancing MOSFETs with programmable timers and diagnostic monitoring.

Applications

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

Procurement Notes

Verify the specific suffix 'TB1' against official documentation to confirm feature set variations such as channel count or safety level. Confirm end-of-life status as some sources indicate obsolescence for this series. Ensure compatibility with required isolation transceivers like the MC33664 for TPL implementation.

Selection Notes

Select this model for applications requiring six-cell management with isolated communication. Compare against the MC33772BTC0AER2 variant which may offer different safety integrity levels or channel configurations. Evaluate thermal performance requirements given the LQFP-48 package constraints for high-current balancing operations.

Part Context

This component belongs to the MC33772B family of lithium-ion battery cell controllers. It is engineered for automotive and industrial environments, supporting ISO 26262 functional safety standards. The device integrates analog front-end capabilities with digital control interfaces for comprehensive battery stack monitoring.
