Product details

Active production, CAN-based battery monitor for multi-chemistry packs

The NXP MM9Z1I638BM2EP is a Battery Monitor IC in a 48-VFQFN Exposed Pad package, designed for multi-chemistry battery stacks including lithium-ion and lead-acid.

Multi-chemistry flexibility and CAN bus integration

Multi-Chemistry support means one BOM line covers Li-ion, LiFePO4, lead-acid, or NiMH chemistries without swapping the monitor IC — useful when a platform spans different battery types across model variants.

48-QFN-EP footprint and thermal handling

The pad is the main thermal path — without proper soldering to the PCB copper, junction temperature rises quickly under continuous monitoring load.

Frequently asked questions

Is the MM9Z1I638BM2EP compatible with lithium-ion batteries?

Yes, the Multi-Chemistry designation means it supports lithium-ion, LiFePO4, lead-acid, and other chemistries without hardware changes.

What interface does the MM9Z1I638BM2EP use?

It uses a CAN interface, integrating the transceiver on-chip for direct connection to a CAN bus.
