What the battery monitor does for a Li-Ion pack
The DS2762AE+ is a dedicated battery monitor for Lithium-Ion chemistries, handling the key measurements and protections a single-cell Li-Ion pack needs in a portable device. Its 1-Wire interface means the host microcontroller talks to it over a single data line plus ground — useful when board space or connector pins are tight. The monitor integrates fault protection for over-current, over-voltage, under-voltage, and short-circuit conditions, so the pack doesn't rely solely on a separate protector IC.
Package, temperature, and board-fit
Housed in a 16-TSSOP (4.40 mm width) surface-mount package, the DS2762AE+ fits on a compact PCB alongside the battery connector and passives. The operating temperature range of -20°C to 70°C covers consumer and industrial indoor use — not suitable for extended automotive or high-temp environments.
Lifecycle and compliance
It is ROHS3 compliant, meaning it meets the latest EU restriction on hazardous substances for electronic components.
