It reports voltage, current, and accumulated charge over the I²C bus to a host microcontroller. The 10-TDFN (3x4 mm) package with exposed pad suits compact portable designs—think handheld instruments, medical monitors, or consumer electronics where board space is tight and the battery is a single series cell. ## Key ratings and what they mean for the BOM Single-cell support locks this part to 1S packs only—if your BOM calls for a 2S or 3S stack, this monitor won't work without external cell-balancing circuitry. The I²C interface keeps the bus wiring simple: two lines to the host MCU, no extra level shifters if the host runs at the same logic voltage. Operating temperature from -20°C to 70°C covers indoor and most consumer environments but excludes automotive cabin or outdoor telecom enclosures where ambient can push past 70°C. The exposed pad needs a thermal land on the PCB—skipping that connection leaves the die hotter than the datasheet intends. ## Lifecycle and sourcing reality For dual-sourcing or supply resilience, no official second source is listed in the record, so plan for single-sourced BOM lines unless you qualify an alternate independently.","metaTitle":"DS2782G+T&R Battery Monitor, Li-Ion/Polymer, I²C, 10-TDFN","metaDescription":"DS2782G+T&R single-cell Li-Ion/Polymer battery monitor with I²C interface.
