Analog Devices Isolated Gate Drivers
Analog Devices’ ADuM4122 Isolated Gate Driver is an adjustable slew rate driver that uses iCoupler technology to provide precision isolation. The ADuM4122 uses a high-frequency carrier and iCoupler chip-scale transformers to provide 5000Vrms of true galvanic isolation between input and output regions.
The architecture of the ADuM4122 also provides high immunity to common-mode transients, electrical noise, and magnetic interference.
The input side operates from a 3.3V to 6.5V input for compatibility with lower voltage systems, while the output side operates from a 4.5V to 35V supply. The output side features two 2A outputs, with one that can be set to a high impedance state, reducing the output slew rate for controlling EMI and voltage overshoot.
The ADuM4122 can operate with a junction temperature up to 125°C and has an integrated thermal shutdown.
