6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)(2)(3)
MIN MAX UNIT
VIN pin voltage –0.3 6 V
SCL, SDIO, HWEN, PWM pin voltages –0.3 (VIN + 0.3 V) with 6 V maximum V
IDxx pin voltages –0.3 (VVOUT + 0.3 V) with 6 V maximum V
Continuous power dissipation(4) Internally limited
Junction temperature, tJ-MAX 150 °C
Maximum lead temperature (soldering) See(5) °C
Storage temperature, Tstg –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) All voltages are with respect to the potential at the GND pins.
(3) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications. All voltages are with respect to the potential at the GND pins.
(4) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 150°C (typical) and disengages at TJ = 125°C (typical).
(5) For detailed soldering specifications and information, see Texas Instruments Application Report AN-1112 DSBGA Wafer Level Chip Scale Package.
