lntelligent power switch

www.DataSheet4U.com TDE1707DF 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 Thermal shutdown GND and VS open wire protection Adjustable delay at switch on Indicator status LED driver +5V regulated AUX. voltage High burst immunity Especially dedicated to proximity detectors, its internal +5V supply can be used to supply external circuits (See also AN495/0692). 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.. DFN (4x4) Description The TDE1707DF is a 0.5A 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) Order codes Part number TDE1707DF TDE1707DFT Temp range, °C -25°C to +85°C -25°.
