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. 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCCA Supply voltage on A-side –0.5 4 V VCCB Supply voltage on B-side –0.5 4 V VEN Enable input voltage –0.5 4 V VI/O I2C bus voltage –0.5 4 V IOL Maximum SDAA, SCLA IOL current 20 mA IIK Input clamp current (SDAB/SCLB) –20 mA Input clamp current (EN, VCCA, VCCB, SDAA, SCLA) –20 mA IOK Output clamp current (SDAB/SCLB) –20 mA Output clamp current (EN, VCCA, VCCB, SDAA, SCLA) –20 mA Operating junction temperature TJ 130 °C Storage temperature Tstg –60 150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 7.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS- 001, all pins(1) ±2000 V Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000 7.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT TA Operating free-air temperature –40 125 °C VCCA Supply voltage 0.8 3.6 V VCCB Supply voltage 1.65 3.6 V VI/O Input-output voltage SDAA, SCLA 0 3.6 V SDAB, SCLB 0 3.6 EN 0 3.6 (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report. 7.4 Thermal Information THERMAL METRIC(1) TCA9802 UNIT DGK (VSSOP) 8 PINS RθJA Junction-to-ambient thermal resistance 174.1 °C/W RθJC(top) Junction-to-case (top) thermal resistance 85 °C/W RθJB Junction-to-board thermal resistance 104.4 °C/W ΨJT Junction-to-top characterization parameter 18.3 °C/W ΨJB Junction-to-board characterization parameter 102.8 °C/W |
