11.1.1.1 Using TINA-TI SPICE-Based Analog Simulation Program with the TMP20

NOTE

These files require that the TINA software (from DesignSoft) or TINA-TI software be installed. Download the free TINA-TI software from the TINA-TI folder.

TMP20 ai_tina_therm_elec_bos466.gif
1. The TMP20 TINA model is preliminary only.
2. Parameters and definitions:
  1. Tobject = Temperature of the object to be cooled (in °C)
  2. Vset = Voltage that corresponds to the desired output temperature from the TMP20
  3. VTEMP = Voltage output of the TMP20
  4. Hotplate = TEC plate on opposite side of object
  5. Coldplate = TEC plate in contact with object
3. In this configuration, the TEC driver can cool to –T°C and heating to 41°C; the Vset range is 1.38 V to 1.95 V. The OPA569 device outputs = ±1.65 A, ±0.5 V to ±4.5 V. The 10-MΩ resistors are for TINA convergence.
4. For convergence in TINA software: In Analysis/Set Analysis Parameters menu, set shunt conductance = 1 p.
