It integrates fuel-gauging, protection, and communication over a 1-Wire interface, letting a host MCU read battery state-of-charge, voltage, current, and temperature on a single data line. Typical deployment is in handheld instruments, medical devices, portable terminals, and any design where a sealed battery pack needs accurate capacity reporting and safety monitoring. ## Key features and what they mean for your BOM The part manages a single Li-Ion or Li-Poly cell (Number of Cells: 1). Fault protection covers overcurrent, overvoltage, undervoltage, and short circuit. This means the DS2784G+ can serve as the primary safety monitor in a pack, eliminating a separate protector IC and saving board area in the cramped space of a 14-TDFN package. The 1-Wire interface (Interface: 1-Wire) reduces the interconnect between the battery pack and the host to a single data line plus ground. That simplifies the pack connector and wiring harness, but the protocol is proprietary to Maxim — the host side needs a 1-Wire master (often integrated in the host MCU or added via a small bridge IC). ## Sourcing and lifecycle reality The DS2784G+ carries an Active lifecycle status per Maxim's product records. For a BOM line that needs a qualified battery-management controller, this part is safe to specify into new designs and ongoing production builds. The ROHS3 compliance (ROHS3 Compliant) covers global regulatory requirements for lead-free assembly.","metaTitle":"DS2784G+ Multi-Function Controller, 1-Cell Li-Ion, 1-Wire","metaDescription":"DS2784G+ Multi-Function Controller for 1-cell Li-Ion/Polymer batteries. 1-Wire interface, fault protection, -40°C to 85°C, 14-TDFN.
