What this part does on the board
The MAX6432ORUS-T is a multi-chemistry battery monitor from Analog Devices that tracks charge state across two series cells. It accepts any common lithium, NiMH, or lead-acid chemistry without per-cell configuration — the chemistry-agnostic front end handles the voltage curve internally. Housed in a SOT-23-4 (TO-253-4 / TO-253AA) surface-mount package, it fits into compact portable or backup-power designs where board area is tight.
It is RoHS non-compliant per the current listing, so confirm your assembly's exemption or waiver before committing the BOM.
