The TDE1707 is an industrial I.P.S. (intelligent power switch). Dedicated to proximity detectors, it can deliver up to 0.5 A to a ”configurable” load (load to battery or load to ground configuration); see block diagram fig.1. On the application circuit (fig. 2) of the TDE1707 Data-Sheet, the use of filter capacitors is recommended on both :- - The power supply (+Vs pin 7). - The +5 V regulated voltage (Vreg pin 6).
