Digital isolators are used in a variety of applications where the complete electrical isolation of two systems or components is necessary. One such product is the TJF1052IT/5Y digital isolator. This isolator is a capacitive Type III device with a high-level pulsewidth modulation (PWM) technique. It operates under the influence of transient voltage suppression (TVS) and contains 2-elements in 1 package.

The TJF1052IT/5Y digital isolator can be used in many applications which require digital information exchange between isolated systems. Some common uses include industrial control systems, motor control systems, home automation, lighting control, and medical instrumentation.

This isolator contains a mounting base, a signal/ground connection, and a power input/output connection. The signal and ground connection is made via the pins of the isolator, while the power is supplied both on the input and output side of the isolator. This means that the TJF1052IT/5Y supports dual voltage operation.

The working principle behind this isolator consists of two components working independently of each other. First, the AC signal is transformed into a series of high and low levels known as “bits”. These bits are then encoded into a pulsewidth modulation (PWM) signal. The PWM signal is then sent across an isolation barrier. A comparator circuit on the other side of the isolation barrier then interprets the encoded PWM signal and converts it back to the original AC signal.

The TJF1052IT/5Y isolator has excellent data isolation performance with a VOUT CMR rating of greater than 95dB and VOUT CMRR of greater than 65dB. Furthermore, the device is designed to be immune to electrical noise on the input and output side, making it ideal for use in noisy environments.

The TJF1052IT/5Y digital isolator is a reliable and efficient device designed to work in a variety of applications which require electrical isolation of two systems or components. It is robust and designed to withstand current surges, making it a reliable solution for many digital isolation applications.
