• Uninterruptible Power Supply (UPS) units

Procurement Notes

Verify the specific suffix 'TA2' against official NXP documentation to confirm channel count and package type. Ensure compatibility with existing PCB footprints for the LQFP-EP-64 configuration. Confirm that the AEC-Q100 grade meets your project's automotive qualification requirements before finalizing procurement.

Selection Notes

Select this component when an 8-channel solution is required for high-voltage lithium-ion stacks. The TA2 variant specifically denotes the advanced feature set and LQFP64 packaging. Compare against the TP2 variant if different pinout or thermal performance characteristics are needed for the specific application design.

Part Context

This part belongs to the MC33771C family of battery cell controllers designed for premium applications. It complements other variants like the MC33771CTP2AER2, differing primarily in package style and specific feature configurations. The series targets demanding automotive and industrial energy storage markets requiring robust cell balancing and monitoring.

Replacement Considerations

Direct substitutes include other MC33771C variants such as MC33771CTP2AER2, provided the package and feature set align with the design. Verify electrical parameters and pin compatibility before swapping.
