2 / 20 page DS2764 High-Precision Li+ Battery Monitor with 2-Wire Interface 2 of 20 ABSOLUTE MAXIMUM RATINGS Voltage Range on PLS and CC Pins, Relative to VSS -0.3V to +18V Voltage Range on Any Other Pin, Relative to VSS -0.3V to +6V Continuous Internal Sense Resistor Current ±2.5A Pulsed Internal Sense Resistor Current ±50A for <100µs/s, <1000 pulses Operating Temperature Range -40°C to +85°C Storage Temperature Range -55°C to +125°C Soldering Temperature See IPC/JEDEC J-STD-020A Specification 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. RECOMMENDED DC OPERATING CONDITIONS (2.5V £ VDD £ 5.5V, TA = -20°C to +70°C.)
