Procurement Notes

Verify the specific ordering suffix TP1AE to confirm the LQFP-48 package variant and tape-and-reel or tray packaging configuration as listed by the distributor. Ensure compatibility with the required isolation topology, such as pairing with the MC33664 transceiver for daisy-chain networks. Confirm RoHS compliance and REACH SVHC status through the manufacturer's material declaration before final procurement.

Selection Notes

Select this model for applications requiring six-cell monitoring with integrated balancing and high functional safety support up to ASIL D. It is suitable for designs needing either isolated daisy-chain communication for cost-effective multi-node setups or direct SPI interfaces. Consider the thermal performance of the LQFP-48 package and ensure the system voltage remains within the specified operational limits during transient events.
