PC33772ASP1AE

Battery Management Overview

The MC33772ASP1AE is a premium battery cell controller IC from NXP Semiconductors, designed for high-voltage lithium-ion battery management systems. It features six dedicated voltage measurement channels and supports stack voltage monitoring with a maximum total voltage measurement error of 0.8 mV. The device integrates an analog-to-digital converter for differential cell voltages, currents, and temperature measurements, alongside a built-in coulomb counter. It includes onboard passive balancing MOSFETs rated at 300 mA with low on-resistance and diagnostic capabilities. Communication interfaces include isolated daisy chain via transformer coupling or standard SPI, supporting up to 4 Mbps data rates. The component operates within a supply voltage range of 6 V to 30 V, with transient tolerance up to 40 V, and complies with AEC-Q100 automotive qualification standards.

Battery Management Feature Summary

• Integrates six-channel differential voltage measurement with advanced ADC conversion and integrated coulomb counting for precise state estimation.
• Features onboard 300 mA passive balancing MOSFETs with programmable timers and comprehensive fault diagnostics including OV/UV and OT/UT monitoring.
• Supports flexible communication through isolated transformer-coupled daisy chain or standard SPI interfaces for robust MCU integration.

Battery Management Applications

• Battery control systems for electric vehicles (EV)
• Energy storage system (ESS) applications
• Uninterruptible power supply (UPS) architectures

Battery Management Procurement Notes

Verify the specific suffix ASP1AE 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 selected variant meets the required thermal operating range and functional safety integrity levels for the target application environment before finalizing procurement orders.

Battery Management Selection Notes

Select this model when a six-channel architecture suffices for the battery pack topology. Compare against the MC33772CTP1AE if current sensing requirements differ significantly. Consider the MC33771 series for higher channel counts exceeding six cells. Validate that the 30 V supply limit aligns with the system's maximum stack voltage and transient conditions during operation.

Battery Management Part Context

This component belongs to the MC33772C family of battery cell controllers, which are optimized for automotive and industrial lithium-ion applications. The family provides scalable solutions ranging from three to six channels, featuring integrated balancing and advanced diagnostic functions. These devices support ISO 26262 functional safety standards up to ASIL D, ensuring reliability in critical power management environments.

Battery Management Replacement Considerations

MC33772CTP1AE serves as a direct alternative within the same product family offering identical six-channel functionality and pinout compatibility. Verify that any substitute part matches the specific packaging and quality grade requirements of the original design specification.
