  • Der Emitter wird mit 10mA gepulst betrieben; das bedeutet, dass jeder Widerstand in Serie zu Vcc einen Spannungsabfall in der Versorgungsleitung verursacht. 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 m ode; 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 Empfohlener Arbeitsbereich Recommended Operating conditions Bezeichnung Parameter Symbol Symbol Wert Value Einheit Unit Min Max Betriebstemperatur Full operational ambient temperature range ΤA -20 +65 °C Versorgungsspannung Supply voltage Vcc 2.3 3.6 V Versorgungsspannungsstörungen * (Frequenzbereich: 0...20kHz) Supply voltage noise (frequency range: 0...20kHz) dVcc pp 0.2 V Ausgangsspannung Output voltage Vo 1.7 3.6 V Pull-up Widerstand Pull-up resistance Rpull up 10 100 kOhm

Startverhalten und Ablaufdiagramm Start-up behavior and Timing diagramm Der Ausgang ist immer hochohmig, wenn an Vcc keine Spannung angeschlossen ist. Wenn die Versorgungsspannung Vcc , start erreicht, bleibt der Ausgang für 60ms <tstart <120ms auf „low“. Anschließend findet etwa alle 90ms eine Messung der Orientierung statt und der Ausgang wird entprechend geschalten. The Output is always high ohmic when voltage at V cc is not connected. When supply voltage reaches V cc, start the sensor output stays low for 60ms <tstart <120ms. Subsequently approx. every 90ms the orientation is measured and the output is set accordingly.
