IC FOR PROXIMITY DETECTOR GENERAL DESCRIPTION AM 313 The AM 313 is a bipolar monolithic Integrated Circuit designed for proximity detection applications. The function is based on the damping of an LC oscillator which switches a transistor and LED output. FEATURES Wide Supply Voltage Range from 4.75 to 35V Supply Current Without Oscillator typical 1mA Complementary Outputs with Short–Circuit Protection P–Type Drivers for PNP Bipolar and PMOS Transistors Adjustable Output Current From 100A to 12mA Adjustable Detection Distance and Hysteresis Adjustable Temperature Compensation for Detection Distance Protection against False Polarity Power–On–Delay LED Output 4mA typical BLOCK DIAGRAM VCC CABT 14 Power-On Level 5 VREF RK LC RD RH 7 2 1 16 15 Hysteresis Oscillator Voltage Reference Power-On Delay Short-Circuit Detection 11 10 9 8 RM Q Q RS Rectifier Schmitt Trigger Amplifier Output Stages Drive Current LED 4 Figure 1 CGL 3 LED 6 GND analog microelectronics Analog Microelectronics GmbH An der Fahrt 13, D – 55124 Mainz Internet: www.analogmicro.de Phone: +49 (0)6131/91 073 – 0 Fax: +49 (0)6131/91 073 – 30 E–Mail: info@analogmicro.de April 2005 1/4 IC FOR PROXIMITY DETECTOR ELECTRICAL SPECIFICATIONS Tamb = 25°C, VCC = 4.75 to 35 V Parameter Supply Current Symbol ICC Conditions VCC = 4.75V, IRd = 0A VCC = 4.75V, IRd = 220A VCC = 35V, IRd = 0A Output Source Current Output Sink Current Max.
