Description
General part information
TDE1708DFT Series
The TDE1708DFT is an Integrated Power Switch with up to 48V Power supply capability. Two output configurations are possible:Load to Gnd. (High Side Mode)Load to VS (Low side Mode)
Especially dedicated to proximity detectors, its internal +5V supply can be used to supply external circuits (See also AN495).
A signal is internally generated to block the In signal, and prevent activation of the output switch, as long as an abnormal condition is detected. The power-on transition, as well as the chip over temperature and the output overcurrent, concur to the generation of such signal. A minimum delay of 25ms (Typ.value) is added to the trailing edge of such signal to ensure that a stable normal situation is present when the signal disappears. The delay (of the disappearance of the block signal; no delay at its on set) can be further increased connecting a capacitor between pin3 and ground. It can drive resistive or inductive loads.
