The MAX6432DHUS-T from Maxim Integrated is a battery monitor IC designed to supervise two series-connected cells of any chemistry — Li-ion, NiMH, NiCd, or lead-acid. It reports undervoltage and overvoltage conditions, acting as a watchdog for the battery stack in portable and backup-power equipment.
The four-pin layout keeps routing simple for a monitor function — no external passives beyond the usual decoupling and voltage-divider network.
No, the MAX6432DHUS-T is Active in production — no end-of-life notice has been issued. It is suitable for new designs and ongoing production BOMs.
It monitors two series-connected battery cells of any chemistry, detecting undervoltage or overvoltage conditions. Typical applications include portable instruments, backup battery packs, and industrial equipment where the battery stack must stay within safe voltage limits.
