Thermoelectric Cooler (TEC) Controller ADN8831 GENERAL DESCRIPTION
... The ADN8831 is a controller for a thermoelectric cooler (TEC). The voltage applied to the input of the ADN8831 corresponds to the target temperature set point. The appropriate current is then applied to the TEC to pump heat either to, or away from, the object whose temperature is being regulated. Th ...

Advantages of IC-Based Hot-Swap Circuit
... Inrush current to the load is, therefore, limited to a level proportional to the load capacitance and the constant slew rate: ILIMIT (typ) = C LOAD × 9V/ms. After Q1 is fully enhanced and the load voltage is settled to its final value, the voltage drop across Q1 (ILOAD × R DS(ON) ) is monitored for ...
