Li-Ion battery monitor with 1-Wire interface
The Maxim Integrated DS2762AE+T&R is a Li-Ion battery monitor that tracks charge, voltage, current, and temperature over a single 1-Wire interface. It integrates over-current, over/under-voltage, and short-circuit fault protection — the full protection set for a single-cell Li-Ion pack. The 1-Wire bus means only one data line plus ground to the host, which simplifies wiring in portable equipment where connector pins are tight.
Temperature grade and package — what they mean for the build
Rated for -20°C to 70°C ambient. The 16-TSSOP package (4.40 mm width) is a fine-pitch surface-mount part that reflows with standard lead-free profiles.
Lifecycle and sourcing posture
ROHS3 compliant, so no conflict with EU or California restricted-substance rules. No official second source or pin-compatible drop-in is listed on the manufacturer cross-reference, so dual-sourcing would require a board-level redesign to a different monitor family.
