VOLTAGE DESCRIPTION The TDE1707 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) Especially dedicated to proximity detectors, its inBLOCK DIAGRAM July 1992 SO8 ORDERING NUMBER: TDE1707FP ternal +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 overtemperature and the output overcurrent, concurr to the generation of such signal. A minimum delay of 25µs (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 disapperance 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. 1/6 This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.

It can source or sink current (Iold typ = 3mA), according to the output configuration chosen. The thresholds, represented by the output comparator in the Block Diagram, are set at about 1.5V - 2V. For instance, in the High Side Load case of the A V 300 100 3 300 Vreg 6 Oldlk 1 0.5 µA µA V mV µA 2 5 4.5 5 5.5 V 6 30 50 mA 6 4 mA mA 3 4 mA 1.2 1.6 V 2 2 4 10 µA 6 µA 4 V Application Circuit, when the voltage on pin 8 (the output) differs from VCC less than 1.5V, the output is sensed in ”OFF” state and the LED driver is disabled. If instead pin 8 differs from VCC more than 3V (the output comparator threshold value plus the drop voltage on the LED), then the output is sensed ”ON” and the driver will force the current on the LED.
