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 RECOMMENDED OPERATING CONDITIONS MIN NOM MAX UNIT Supply voltage, VCC 2.6 4.5 V Operating free-air temperature, TJ −20 70 °C Input voltage range at SRP and SRN, (with respect to VSS) −100 100 mV ELECTRICAL CHARACTERISTICS TJ = −20°C to 70°C, TJ = TA, 2.6 V ≤ VCC ≤ 4.5 V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT INPUT CURRENTS ICC(ACT) Active current VCC > VCC(min) 60 90 ICC(SLP) Sleep current 1.2 2.5 A ICC(SHP) Ship current 0.9 1.7 µA ICC(POR) Hibernate current 0 V < VCC < V(POR) 0.6 1.5 RBI current RBI pin only, VCC < V(POR) 20 nA V(POR) POR threshold 2.05 2.55 V POR threshold hysteresis 100 mV Input impedance on BAT pin 10 M Ω Input impedance on SRP, SRN pins 10 M Ω VOLTAGE MEASUREMENT Measurement range VCC = VI(BAT) 2.6 4.5 V Reported voltage resolution 1 mV Reported accuracy −20 20 mV Voltage update time 2 s TEMPERATURE MEASUREMENT Reported temperature resolution 0.25 °K Reported temperature accuracy −3 3 °K Temperature update time 2 s |
