(2) The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the IN or OUT pins. A tight layout minimizes switching noise. 7.4 Thermal Information bq241xx THERMAL METRIC (1) RHL (VQFN) UNIT 20 PINS RθJA Junction-to-ambient thermal resistance 39.2 °C/W RθJC(top) Junction-to-case (top) thermal resistance 39.3 °C/W RθJB Junction-to-board thermal resistance 15.8 °C/W ψJT Junction-to-top characterization parameter 0.6 °C/W ψJB Junction-to-board characterization parameter 15.8 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 3.6 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 7.5 Electrical Characteristics TJ = 0°C to 125°C and recommended supply voltage range (unless otherwise stated) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT INPUT CURRENTS VCC > VCC(min), PWM switching 10 mA I(VCC) VCC supply current VCC > VCC(min), PWM NOT switching 5 VCC > VCC(min), CE = HIGH 315 μA 0°C ≤ TJ ≤ 65°C, VI(BAT) = 4.2 V, 3.5 VCC < V(SLP) or VCC > V(SLP) but not in charge Battery discharge sleep current, (SNS, 0°C ≤ TJ ≤ 65°C, VI(BAT) = 8.4 V, I(SLP) 5.5 μA BAT, OUT, FB pins) VCC < V(SLP) or VCC > V(SLP) but not in charge 0°C ≤ TJ ≤ 65°C, VI(BAT) = 12.6 V, 7.7 VCC < V(SLP) or VCC > V(SLP) but not in charge VOLTAGE REGULATION CELLS = Low, in voltage regulation 4.2 Output voltage, bq24103/03A/04/13/13A VOREG CELLS = High, in voltage regulation 8.4 V Output voltage, bq24100/08/09 Operating in voltage regulation 4.2 Feedback regulation REF for bq24105/15 VIBAT IIBAT = 25 nA typical into pin 2.1 V only (W/FB) TA = 25°C –0.5% 0.5% Voltage regulation accuracy –1% 1% CURRENT REGULATION - FAST CHARGE VLOWV ≤ VI(BAT) < VOREG, IOCHARGE Output current range of converter 150 2000 mA V(VCC) - VI(BAT) > V(DO-MAX) 100 mV ≤ VIREG≤ 200 mV, VIREG Voltage regulated across R(SNS) Accuracy –10% 10% Programmed Where 5 k Ω ≤ RSET1 ≤ 10 kΩ, Select RSET1 to program VIREG, VIREG(measured) = IOCHARGE + RSNS (–10% to 10% excludes errors due to RSET1 and R(SNS) tolerances) V(LOWV) ≤ VI(BAT) ≤ VO(REG), V(ISET1) Output current set voltage 1 V V(VCC) ≤ VI(BAT) × V(DO-MAX) Copyright © 2004–2015, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: bq24100 bq24103 bq24103A bq24104 bq24105 bq24108 bq24109 bq24113 bq24113A bq24115 |
