TMTV Thermal Operation

The heater located within the TMTV die should be accessed by connecting two sets of eight (8)
solder balls to each side of a power supply in parallel. The heater consists of a resistor and the
polarity of the power supply connections is arbitrary. The package balls to access the heater are
identified in Table 4. Ball reference designations can be found in Figure 4 and Figure 5. A graphical
representation of the die heater and its connections are shown in Figure 6.
