TDE1707-Intelligent Power Switch
The TDE1707 is a 0.5A integrated power switch capable of supplying up to 48V. Two output configurations are possible:
- Loaded to GND. (high side mode)
- Loaded to VS (low side mode) especially dedicated to proximity detectors, its internal +5 V supply can be used for external supply circuits (see also AN495/0692). Internally is a signal generating block signal that prevents the output switch from activating as long as an abnormal condition is detected. Transitions on the power supply, as well as chip overheating and output overcurrent, concurr to generate such signals. A minimum delay time of 25ms (typ) is added to the falling edge of this signal to ensure a stable, normal condition exists when the signal disappears. Delay (signal in the disapperance block; no delay in its sleeve) can be added by connecting a capacitor further between pin 3 and ground. It can drive resistive or inductive loads. ...
