These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
GENERAL INFORMATION
Terminal Assignment
The TAS5111 is offered in a thermally enhanced 32-pin
TSSOP surface-mount package (DAD), which has the
thermal pad on top.

(1) Stresses beyond those listed under “absolute maximum ratings”
may cause permanent damage to the device. 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.
(2) The duration of a voltage spike should be less than 100 ns.
(3) GREG is treated as an input when the GREG pin is overdriven by
a GVDD voltage of 12 V.

See Note 1
(1) The TAS5111 package is thermally enhanced for conductive
cooling using an exposed metal pad area. It is impractical to use the
device with the pad exposed to ambient air as the only means for
heat dissipation.
For this reason, RθJA, a system parameter that characterizes the
thermal treatment, is provided in the Application Information section
of the data sheet. An example and discussion of typical system
RθJA values are provided in the Thermal Information section. This
example provides additional information regarding the power
dissipation ratings. This example should be used as a reference to
calculate the heat dissipation ratings for a specific application. TI
application engineering provides technical support to design
heatsinks if needed. Also, for additional general information on
PowerPad packages, see TI document SLMA002.
