Tripath Technology, Inc. - Technical Information

Note 11: These supply voltages are calculated using the IVPPSENSE and IVNNSENSE values shown in the

Electrical Characteristics table. The typical voltage values shown are calculated using a RVPP and RVNN

values without any tolerance variation. The minimum and maximum voltage limits shown include either a

+1% or –1% (+1% for Over-voltage turn on and Under-voltage turn off, -1% for Over-voltage turn off and

Under-voltage turn on) variation of RVPP or RVNN off the nominal 357kohm, 324kohm, and 976kohm

values. These voltage specifications are examples to show both typical and worst case voltage ranges for

the given RVPP and RVNN resistor values. Please refer to the Application Information section for a more

detailed description of how to calculate the over and under voltage trip voltages for a given resistor value.

Note 12: The fact that the over-voltage turn on specifications exceed the absolute maximum of +/-60V for the TK2150

does not imply that the part will work at these elevated supply voltages. It also does not imply that the

TK2150 is tested or guaranteed at these supply voltages. The supply voltages are simply a calculation

based on the process spread of the IVPPSENSE and IVNNSENSE currents (see note 7). The supply

voltage must be maintained below the absolute maximum of +/-60V or permanent damage to the TK2150

may occur.

Electrical Characteristics TP2150 (Note 13)

TA = 25 °C. See Application/Test Circuit on page 7. Unless otherwise noted, the supply voltage is

Note 13: Minimum and maximum limits are guaranteed but may not be 100% tested.

Note 14: The difference in the VPP and VNN current draw is due to the VN10 regulator sourcing current to the

VNN supply.
