TDE1707DFT Intelligent power switch Features 0.5A output current Low side or high side switch configuration 6V to 48V supply voltage range Overload and short circuit protections Internal voltage clamping Supply and output reversal protection DFN (4x4) Thermal shutdown GND and V open wire protection S Adjustable delay at switch on Especially dedicated to proximity detectors, its in- Indicator status LED driver ternal +5V supply can be used to supply external +5V regulated AUX. voltage circuits (See also AN495). A signal is inter-nally High burst immunity generated to block the In signal, and prevent activation of the output switch, as long as an ab- normal condition is detected.

A minimum delay of 25ms (Typ.value) Switch with up to 48V Power supply capability. is added to the trailing edge of such signal to Two output configurations are possible: ensure that a stable normal situation is present Load to GND. (High Side Mode) when the signal disappears. The delay (of the Load to VS (Low side Mode) 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..
