DS2780 Standalone Fuel Gauge IC

ABSOLUTE MAXIMUM RATINGS

Voltage Range on Any Pin Relative to VSS -0.3V to +6.0V

Voltage on VIN Relative to VSS -0.3V to (V_DD + 0.3V)

Operating Temperature Range -40°C to +85°C

Storage Temperature Range -55°C to +125°C

Soldering Temperature (10s) See JEDEC J-STD-020

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.
