Features

  1. Two built-in detection voltages 1.18V / 1.06V typ. 2. High precision detection voltages ±1% typ. 3. Low current consumption During detection ; 15 µA typ. During waiting ; 15 µA typ. 4. Setting possible during non-induction It is possible to set a time period for which detection is ignored, as for example when voltage drops due to temporary heavy loads. 5. Ripple absorption pins It is possible to check fluctuations in detection through continuous rippling. 6. Built-in hysteresis voltage Package SOP-8D (MM1210XF) Absolute Maximum Ratings Item Rating Storage temperature -40~+125°C Operating temperature -20~+70°C Input voltage 5V Output pin voltage 5V Allowable loss 300mW
