MC33772CTP2AER2

Battery Management Overview

The MC33772CTP2AER2 is a six-channel lithium-ion battery cell controller IC manufactured by NXP USA Inc. Designed for automotive and industrial applications, it manages 3 to 6 battery cells within a stack. The device integrates ADC conversions for differential cell voltages, currents, and temperature measurements, alongside an onboard coulomb counter. It supports isolated transformer physical layer (TPL) communication via SPI or daisy chain interfaces with up to 63 nodes. Key features include passive balancing MOSFETs, advanced diagnostics, and compliance with AEC-Q100 standards.

Battery Management Feature Summary

• Integrated six-channel voltage measurement with averaging capabilities and total stack voltage monitoring
• Onboard passive balancing using low on-resistance MOSFETs with programmable timers and diagnostic functions
• Supports isolated Transformer Physical Layer (TPL) daisy chain communication with loopback capability
• Includes integrated current sensing with PGA and coulomb counting for precise state estimation

Battery Management Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) battery management systems
• High-voltage battery packs in automotive applications
• Energy storage systems (ESS)
• Uninterruptible power supply (UPS) systems

Battery Management Procurement Notes

Verify the specific suffix 'TP2' against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with the intended communication interface, as TPL variants differ from standard SPI-only versions. Confirm RoHS3 compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Battery Management Selection Notes

Select this component when designing systems requiring isolated communication between multiple battery controllers in a daisy-chain topology. It is suitable for applications needing integrated passive balancing and high-precision voltage measurement. Consider the 48-pin HLQFP package constraints and ensure the host MCU supports the required SPI or TPL protocols for data exchange.

Battery Management Part Context

This part belongs to the MC33772C family of battery cell controllers, which are optimized for safety-critical automotive environments. The series supports ISO 26262 functional safety standards up to ASIL D. The MC33772C variant specifically enhances communication flexibility compared to earlier models like the MC33772B, offering support for larger node counts in daisy chains.

Battery Management Replacement Considerations

MC33772CTP2AE is a tray-packaged equivalent of the same electrical specification. MC33772CTP1AER2 offers similar functionality but may differ in specific configuration options or software compatibility. Verify pinout and register maps before substituting.
