• Uninterruptible Power Supply (UPS) applications

Procurement Notes

Verify the specific suffix '1AE' against official NXP documentation to confirm exact ordering and packaging details. Ensure compatibility with required functional safety standards such as ISO 26262 ASIL D if applicable to your design. Confirm that the LQFP48 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring six-cell monitoring with high-precision voltage measurement errors. It is suitable for designs needing integrated Coulomb counting and passive balancing without external discrete components. Consider its compatibility with MPC5xxx MCUs and support for both SPI and isolated TPL interfaces when designing the system architecture.
