4 / 41 page LM2743 SNVS276H – APRIL 2004 – REVISED OCTOBER 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings MIN MAX UNIT VCC –0.3 7 V BOOT voltage –0.3 21 V ISEN –0.3 9.5 V All other pins –0.3 VCC + 0.3 V TJ Junction temperature 150 °C Lead temperature (soldering, 10 s) 260 °C Soldering information Infrared or convection (20 s) 235 °C Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge(1) Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(2) 2000 V (1) The human body model is a 100 pF capacitor discharged through a 1.5-k Ω resistor into each pin. (2) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions MIN NOM MAX UNIT VCC Supply voltage range 3 6 V TJ Junction temperature –40 125 °C 6.4 Thermal Information LM2743 THERMAL METRIC(1) TSSOP (PW) UNIT 14 PINS RθJA Junction-to-ambient thermal resistance 107.9 °C/W RθJC(top) Junction-to-case (top) thermal resistance 33.7 °C/W RθJB Junction-to-board thermal resistance 50.7 °C/W ψJT Junction-to-top characterization parameter 1.8 °C/W ψJB Junction-to-board characterization parameter 50 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 4 Submit Documentation Feedback Copyright © 2004–2015, Texas Instruments Incorporated Product Folder Links: LM2743 |
