The ADUM4121-1ARIZ-RL is an isolated gate driver designed specifically for high-voltage applications. It can be used to drive MOSFET, JFET, IGBT, and other switch-mode power supplies. The ADUM4121-1ARIZ-RL provides an isolated drive signal of up to 8 kV with seamless isolation between the high-voltage side and the low-voltage side. The design is also RoHS compliant and certified for industrial applications.The ADUM4121-1ARIZ-RL isolates both AC and DC loads, and it can be used to drive high-voltage loads up to 1000 V. It includes a power MOSFET gate driver and an optical isolator, which provides an isolated interface between the control board and the logic circuit. The gate driver provides an adjustable drive voltage up to 800 V. The optical isolator provides up to 8 kV of common-mode rejection and isolation between the high-voltage side and the low-voltage side. The ADUM4121-1ARIZ-RL has an operating temperature range of -40°C to +125°C.The working principle of the ADUM4121-1ARIZ-RL is based on a combination of an optically isolated gate driver and a power MOSFET: First, the control board passes a logic signal to the optical isolator. This causes the LED on the isolator to light up, thereby providing a signal to the optically coupler, which in turn passes a signal to the power MOSFET. The gate voltage of the MOSFET is then adjusted to the specified voltage with the help of the gate driver. This causes the MOSFET to switch and the load to be driven.The ADUM4121-1ARIZ-RL is ideal for use in applications such as solar inverters, electromagnetic brakes, hysteresis controllers, motor controls, public address systems, reclosers, static switches, and other industrial applications. Its high-voltage isolated drive voltage with seamless isolation provides reliable and consistent performance. This product is not only RoHS compliant, but is also certified by agencies and organizations such as UL/CSA, CEC, FCC Class B, VDE, and CE. The ADUM4121-1ARIZ-RL can provide up to 8 kV of isolation, making it an ideal choice for industrial applications.The specific data is subject to PDF, and the above content is for reference
