Daher wird empfohlen, diesen Serienwiderstand kleiner 10 Ohm zu halten. Die minimale Versorgungsspanung (Vcc min ) darf keinesfalls unterschritten werden. * The emitter is driven with 10 mA in pulsed mode; this means that any series resistor to Vcc causes a voltage drop on the power line. It is recommended to keep the series resistor below 10 Ohm. The supply voltage may not fall below Vcc min 2007-10-16 3 SFH 7710 Kennwerte Characteristics (TA=25C) Bezeichnung Parameter Symbol Symbol Wert Value Einheit Unit Min. Typ. Max.

Wenn die Versorgungsspannung Vcc , start erreicht, bleibt der Ausgang fur 60ms <tstart <120ms auf low". Anschlieend findet etwa alle 90ms eine Messung der Orientierung statt und der Ausgang wird entprechend geschalten. The Output is always high ohmic when voltage at Vcc is not connected. When supply voltage reaches Vcc, start the sensor output stays low for 60ms <tstart <120ms. Subsequently approx. every 90ms the orientation is measured and the output is set accordingly.
