Manufacturer:TI/FAIT Description:An external resistor RCF is recommended be- tween the slider of the control and feedback po- tentiometer. This resistor assures that in the case of input con- trol or input feedback wire interruption the input differential voltage will be within the NEUTRAL ZONE and the motor position remains frozen. The circuit features an overvoltage disable func- tion referred to the supply voltage VS higher than 18V, both outputs are forced to tristate in this con- dition. The thermal overload function disables the out- puts (tristate) when the junction temperature in- creases above the thermal shutdown threshold temperature of min. 150C. For the start of a heavy loaded motor, if the motor current reaches the max. value it is necessary to respect the dynamical thermal resistance junction to ambient. The maximum output current is 0.8A. The maximum junction temperature in this phase should not increase above the thermal shutdown threshold. In case of output disable due to ther- mal overload the output remains disabled till the junction temperature decreases under the thermal enable threshold. This behaviour is assured with the thermal shutdown hysteresis threshold , which minimum value is 20C. Figure 3, 5 and 7 show typical application dia- grams for headlight adjustment applications.
