Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings are conditions under
which operation of the device is specified. Operating Ratings do not imply verified performance limits. For verified performance limits
and associated test conditions, see the Electrical Characteristics table.
(2)
All voltages are with respect to the potential at the GND pin.
(3)
If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4)
Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ=+150°C (typ.) and
disengages at TJ = +135°C (typ.). Thermal shutdown is verified by design.
(5)
For detailed soldering specifications and information, please refer to Texas Instruments Application Note 1112: DSBGA Wafer Level chip
Scale Package (AN-1112)
(6)
The human body model is a 100pF capacitor discharged through 1.5k
Ω resistor into each pin. (MIL-STD-883 3015.7).

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings are conditions under
which operation of the device is specified. Operating Ratings do not imply verified performance limits. For verified performance limits
and associated test conditions, see the Electrical Characteristics table.
(2)
All voltages are with respect to the potential at the GND pin.
(3)
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =
+125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to-ambient thermal resistance of the
part/package in the application (
θJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (θJA × PD-MAX).

(1)
Junction-to-ambient thermal resistance (
θJA) is taken from a thermal modeling result, performed under the conditions and guidelines set
forth in the JEDEC standard JESD51-7. The test board is a 4-layer FR-4 board measuring 102 mm x 76 mm x 1.6 mm with a 2x1 array
of thermal vias. The ground plane on the board is 50 mm x 50 mm. Thickness of copper layers are 36 µm/18 µm/18 µm/36 µm (1.5
oz/1oz/1oz/1.5 oz). Ambient temperature in simulation is 22°C, still air. Power dissipation is 1W.
