These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions " is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 3.2 RECOMMENDED OPERATING CONDITIONS TA = 25°C and VREGIN = VBAT = 3.6V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT No operating restrictions 2.7 4.5 VREGIN Supply voltage V No FLASH writes 2.45 2.7 External input capacitor for internal LDO between CREGIN 0.1 μF Nominal capacitor values specified. REGIN and VSS Recommend a 5% ceramic X5R type External output capacitor for internal LDO between capacitor located close to the device. CLDO25 0.47 1 μF VCC and VSS Fuel gauge in NORMAL mode. ICC Normal operating-mode current(1) 118 μA ILOAD > Sleep Current Fuel gauge in SLEEP+ mode. ISLP+ Sleep+ operating mode current(1) 62 μA ILOAD < Sleep Current Fuel gauge in SLEEP mode.
