3 / 6 page 2008. 7. 3 3/6 TL431 Series Revision No : 0 Input FIGURE 1-TEST CIRCUIT FOR VKA = Vref off I KA V Input FIGURE 3-TEST CIRCUIT FOR I off FIGURE 2-TEST CIRCUIT FOR VKA > Vref IK IK VKA VKA Input R1 R2 Iref VKA = Vref ( 1+ ) + Iref R1 R1 R2 Max. Min. T1 T2 AMBIENT TEMPERATURE - Vref (Min.) Ta = T2 - T1 Vref Vref Vref Vref = Vref (Max.) Vref Example : Vref = 8.0mV and slope is positive, Vref at 25 =2.495V, Ta=70 0.008 10 6 Vref = = 45.8 ppm/ 70 (2.495) Note 2: The dynamic impedance Zka is defined as: VKA |Zka| = Ik When the device is programmed with two external resistors, R1 and R2, (refer to Figure 2) the total dynamic impedance of the circuit is defined as: R1 |Zka’| = |Zka| (1+ ) R2 Note 1: The deviation parameter Vref is defined as the differences between the maximum and minimum values obtained over the full operating ambient temperature range that applies. The average temperature coefficient of the Reference input voltage, Vref , is defined as: Vref ( ) 10 6 ppm Vref at 25 Vref ( ) = Ta Vref 10 6 = Ta(Vref at 25 ) Vref can be positive or negative depending on whether Vref Min. or Vref Max. occurs at the lower ambient temperature. |
