Descriptions:

The DS2782E+T&R is a standalone fuel gauge IC designed to monitor battery voltage, current, temperature, and remaining capacity in single-cell Li-Ion/Li-Polymer battery packs. It communicates via the 1-Wire® interface, enabling simple host communication with minimal wiring. The device includes integrated protection features such as overvoltage, undervoltage, and overcurrent detection.

Features:

• Integrated Current Accumulation (Coulomb Counting) for accurate charge tracking
• Voltage, Current, and Temperature Monitoring
• Low Power Consumption (active and sleep modes)
• 1-Wire Communication Interface for host communication
• Programmable Protection Features (OVP, UVP, OCP)
• 32 Bytes of User EEPROM for parameter storage
• Compact 8-TSSOP Package (suitable for space-constrained designs)
• Industrial Temperature Range (-40°C to +85°C)

This IC is commonly used in smart battery packs, portable medical devices, and handheld electronics for precise battery monitoring and protection.
