Digital isolators have become a popular choice for applications that require a separation between circuits. The TJF1052IT/2Y digital isolator is a single-channel device designed to provide a fast, low-power isolation interface between electrical systems. It features a wide operating voltage range from 5 to 30 V, with guaranteed data rate of 10 Mbps. The TJF1052IT/2Y is an ideal choice for high speed communication between two different power domains that require signal isolation.

Application field

The TJF1052IT/2Y digital isolator can be used in a variety of applications that require safe, isolated communication between electrical systems. Applications include industrial automation, Medical Equipment, automotive, communications systems, consumer electronics, and power supplies. This isolator is ideal for isolated signal transfer between two systems with different voltages, such as between a logic signal and a motor, or between two separate microcontroller systems.

Working principle

The TJF1052IT/2Y digital isolator converts digital signals using four large MOSFETs, an RC circuit, and a voltage reference. When the input signal is active, the four MOSFETs switch on in sequence to generate a pulse waveform, which is then used to charge a capacitor in the output circuit. The voltage level across the capacitor is detected by the voltage reference. The RC circuit then filters out the AC components of the waveform, leaving only the DC component. This DC signal is then used to drive the output stage, which switches on four FETs to generate the isolation output. This process takes place at a high speed, thereby allowing for a low propagation delay across the isolated interface.

The TJF1052IT/2Y digital isolator provides a low-power, high-speed connection between two systems. It features an adjustable propagation delay, low power consumption, and is designed for easy implementation in industrial and consumer applications. This device also offers high signal integrity, with up to 10 Mbps data rate and guaranteed transient isolation protection.
