Product details

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.

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).

The ROHS3 compliance (ROHS3 Compliant) covers global regulatory requirements for lead-free assembly.

Frequently asked questions

Is DS2784G+ compatible with 1-cell Li-Ion batteries?

Yes, the DS2784G+ is designed for single-cell Lithium-Ion and Lithium-Polymer packs. It integrates fuel-gauging, protection, and 1-Wire communication for exactly that chemistry and cell count.

Is DS2784G+ compatible with 2-cell batteries?

No. The DS2784G+ is specified for 1 cell only. Using it with a 2-cell stack would exceed the internal voltage and protection thresholds, risking damage or unsafe operation.

What is the 1-Wire interface protocol used by DS2784G+?

The DS2784G+ uses the standard 1-Wire protocol — a single data line for both communication and power (parasitic or dedicated supply). The host must include a 1-Wire master controller to read the battery data.
