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.
The TAS5102/TAS5103 are available in a thermally enhanced package:
TAS5102 Pad Up 32-pin HTSSOP PowerPAD package (DAD)
TAS5103 Pad Down 32-pin HTSSOP PowerPAD package (DAP)

The 1N and 2N naming convention is used to indicate the required number of PWM lines to the power stage per channel in a specific
mode.
(2)
An overcurrent protection (OC) occurring on A or B causes all channels to shut down. An OC on C or D works similarly. Global errors
like overtemperature error (OTE), undervoltage protection (UVP), and power-on reset (POR) affect all channels.

The TAS5102 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 higher power applications.
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 SLMA002B.
