2 / 22 page ![]() DS2786 Stand-Alone OCV-Based Fuel Gauge 2 of 22 ABSOLUTE MAXIMUM RATINGS Voltage Range on All Pins Except VPROG Relative to VSS -0.3V to +6V Voltage Range on VPROG Relative to VSS -0.3V to +18V Operating Temperature Range -40°C to +85°C Storage Temperature Range -55°C to +125°C Soldering Temperature Refer to the IPC/JEDECJ-STD-020 Specification. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. RECOMMENDED DC OPERATING CONDITIONS (2.5V VDD 4.5V, TA = -20C to +70C.)
