MC33772CTP2AE

Overview

The MC33772CTP2AE is a six-channel lithium-ion battery cell controller IC designed for automotive and industrial applications. It operates within a supply voltage range of 7.0V to 30V, supporting transient voltages up to 42V in SPI mode. The device features six dedicated battery voltage measurement channels with a maximum total stack voltage measurement error of 0.8mV. It includes seven ADC/GPIO/temperature sensor inputs and integrated synchronous advanced current measurement with ±0.5% accuracy from milliamps to kiloamps. The component supports isolated daisy chain or SPI communication and provides onboard passive balancing via 300mA MOSFETs.

Feature Summary

• Integrated six-channel differential voltage measurement with high precision and total stack voltage monitoring capabilities
• Synchronized advanced current measurement with integrated programmable gain amplifier and coulomb counter
• Onboard passive balancing using low Rdson MOSFETs with diagnostic functions and sleep mode support
• Supports ISO 26262 functional safety standards up to ASIL D level with comprehensive fault verification

Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) battery management systems
• High-voltage energy storage systems (ESS)
• Uninterruptible power supply (UPS) systems
• Electric bicycle and scooter battery packs

Procurement Notes

Verify the specific suffix 'TP2' against the official NXP datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the intended microcontroller interface, as the device supports both SPI and transformer-isolated daisy chain modes. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when designing systems requiring precise cell balancing and high-integrity communication in harsh environments. The MC33772CTP2AE is suitable for applications demanding ASIL D safety certification. Consider the 48-LQFP package constraints and thermal dissipation requirements. Evaluate the need for isolated communication if galvanic isolation between the battery stack and host MCU is required.

Part Context

This part belongs to the MC33772C series of battery cell controllers from NXP Semiconductors. It is engineered for high-voltage battery stacks ranging from 48V to 800V. The series is compatible with NXP's MPC5xxx microcontroller families and often used alongside communication gateways like the MC33664 for robust system integration.

Replacement Considerations

Check for direct pin-to-pin replacements within the MC33772 family, such as variants with different balancing currents or communication interfaces. Verify that any substitute maintains the same ASIL D capability and package dimensions.
