Overview
Der Opto 5 Click Board™ ist eine kompakte Zusatzplatine, die unkomplizierte Sicherheitsisolierung von Hochspannung bietet. Diese Platine verfügt über den FOD4216, einen Zufallsphasen-Triac-Treiber ohne Snubber von ON Semiconductor. Der FOD4216 besteht aus einer Infrarot-Emitterdiode, die mit einem hybriden Zufallsphasen-Triac gekoppelt ist, der aus zwei umgekehrt parallelen SCRs besteht, wodurch die Triac-Funktion entsteht, die diskrete Triacs ansteuern kann. Es verwendet eine hocheffiziente Infrarot-Emitterdiode, die eine verbesserte Triggerempfindlichkeit bietet. Dieses Click Board™ ist für Anwendungen wie Hochspannungs-Wechselstromschaltung geeignet, bei denen zwei Schaltkreise in einer Schaltanwendung geschützt und elektrisch isoliert werden müssen.
Das Opto 5 Click Board™ wird durch eine mikroSDK-kompatible Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.

How Does The Opto 5 Click Board™ Work?
The Opto 5 Click Board™ is based on the FOD4216, a random phase snubberless Triac driver that provides uncomplicated high voltage safety isolation from ON Semiconductor. It utilizes a high efficiency infrared emitting diode that offers an improved trigger sensitivity coupled to a hybrid random phase triac formed with two inverse parallel SCRs, which creates the triac function capable of driving discrete triacs. It provides electrical isolation between a low voltage input and a high voltage output while switching the high voltage output.
The Triac stands for triode for alternating current and is a device that can conduct current in either direction when it is triggered or turned on by detecting a light beam on its trigger junction (Gate). The Triac changes from the off-state to the conducting state when a current, or current pulses are applied to the control electrode (Gate). Turning on the device can be achieved while synchronizing with the input voltage, whereas turn-off occurs when the current passes through zero following the control signal removal.
The Opto 5 Click Board™ operates only with the PWM signal from the mikroBUS™ socket that drives the cathode of the FOD4216. In applications when hot-line switching is required, the "hot" side of the line is switched, and the load is connected to the cold or neutral side. In the case of a Standard Triac usage, the user should add a 39Ω resistor and 0.01uF capacitor parallel to triac terminals A1 and A2 used for snubbing of the triac. While in the case of highly inductive loads where the power factor is lower than 0.5), the value of a resistor should be 360Ω. In the case of use Snubberless Triac usage, there is no need for these components.
NOTE: This optoisolator should not be used to drive a load directly. It is intended to be a discrete triac driver device only.
The Opto 5 Click Board™ is designed to operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper, which allows the use of both 3.3V and 5V capable MCUs. This Click board™ comes equipped with a library that contains functions and an example code that can be used, as a reference, for further development.
