2 / 44 page 2-Cell, Stand-Alone, Li+ Fuel-Gauge IC with Protector and Optional SHA-1 Authentication 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VDD = +4.0V to +9.2V, TA = -20°C to +70°C, unless otherwise noted. Typical values are at TA = +25°C.) 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 absolute maximum rating conditions for extended periods may affect device reliability. Voltage Range on PLS, CP, CC, DC Pins Relative to VSS.....................................................-0.3V to +18V Voltage Range on VDD, VIN1, VIN2, SRC Pins Relative to VSS....................................................-0.3V to +9.2V Voltage Range on All Other Pins Relative to VSS ..-0.3V to +6.0V Continuous Sink Current, PIO, DQ......................................20mA Continuous Sink Current, CC, DC.......................................10mA Operating Temperature Range ...........................-20°C to +70°C Storage Temperature Range .............................-55°C to +125°C Soldering Temperature...........................Refer to the IPC/JEDEC J-STD-020 Specification.
