Optoisolators are electronic devices that are designed to provide electrical isolation between two components. The VO0631T is one such optoisolator that is used as an electrically isolated logic outputs. The device has a dual channel MOSFET approach to optocoupling and offers speed-tracking independent of LED current. This article will discuss the application field and working principle of the VO0631T.
The VO0631T is mainly used in optoisolator applications that require a high output speed and track independently of LED current. Examples of these applications are in isolated DC/DC converters for personal computers, air conditioners, and appliances. The device is also suitable for powering isolated power supplies, interconnecting two different power domains, such as a high power domain and a low power domain. Furthermore, it is used in motor speed and position control systems, as well as in remote control transmitters and receivers.
The working principle of the VO0631T is based on the principle of opto-coupling. A light-emitting diode (LED) is connected between the two terminals of the device, which is then energized by a voltage source. When the LED is energized, it emits photons that are detected by a photodetector, such as a phototransistor. The phototransistor then converts the optical signal into an electrical signal, which is then transmitted to the other side of the device. The two terminals on the VO0631T are electrically isolated, which means that a current or voltage can flow through one side without affecting the other.
The VO0631T also features on-chip clamp diodes, which are designed to protect the device against transient voltages and currents. It also has a built-in surge suppression circuit which helps to protect the device against electrostatic discharge (ESD) and other high voltage transients. The device is designed to initiate output at the end of the LED turn-on. Additionally, it has an on-chip MOSFET which is designed to limit the LED output current. The device has a max turn-on time of up to 10µs and an off time of up to 8µs.
In conclusion, the VO0631T is a device that offers electrically isolated logic outputs for applications such as DC/DC converters and interconnecting two different power domains. The device is designed to have a high output speed and track independently of LED current, and features on-chip clamp diodes and surge suppression circuits. With its dual channel MOSFET approach to optocoupling, the device provides an effective way to keep circuits electrically isolated.
