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. All voltage values are with respect to the network ground terminal unless otherwise noted. THERMAL INFORMATION bq2416x THERMAL METRIC(1) UNITS 49 PINS (YFF) 24 PINS (RGE) θJA Junction-to-ambient thermal resistance 49.8 32.6 θJCtop Junction-to-case (top) thermal resistance 0.2 30.5 θJB Junction-to-board thermal resistance 1.1 3.3 °C/W ψJT Junction-to-top characterization parameter 1.1 0.4 ψJB Junction-to-board characterization parameter 6.6 9.3 θJCbot Junction-to-case (bottom) thermal resistance n/a 2.6 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. RECOMMENDED OPERATING CONDITIONS over operating free-air temperature range (unless otherwise noted) MIN MAX UNITS VIN IN voltage range 4.2 18(1) V IN operating voltage range 4.2 10 VUSB USB voltage range 4.2 18(1) V USB operating range 4.2 6 IIN Input current, IN input 2.5 A IUSB Input current USB input 1.5 A ISYS Ouput current from SW, DC 3 A IBAT Charging 2.5 A Discharging, using internal battery FET 2.5 A TJ Operating junction temperature range 0 125 °C (1) The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the BOOT or SW pins. A tight layout minimizes switching noise. Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s): bq24165 bq24166 bq24167 |
