Digital Isolators
Digital Isolators are electronic devices that are used to electrically isolate two circuits from one another, while allowing them to still interact or exchange information. Primarily, they are employed to protect electronic components on both sides of the circuit from voltage surges that might otherwise damage them. THey also protect users from surges that may occur in the external power lines that may cause a spark or electric shock. ADUM1402WSRWZ33 is a type of digital isolator that has unique features which make it particularly suitable for certain applications.
ADUM1402WSRWZ33 Application Field
ADUM1402WSRWZ33 is a isolated gate driver intended for driving MOSFETs and IGBTs at high frequencies of up to 200 kHz. This makes it ideal for use in industrial applications where high frequency switching is required, such as in motor drives, power converters, and various other power electronics applications. It is also suitable for controlling small loads with a low number of power stages such as LED lighting or isolating the digital and analog circuitry in medical implants and diagnostic systems.
ADUM1402WSRWZ33 Working Principle
The ADUM1402WSRWZ33 uses the hybridization of an integrated transformer and two sets of ICs for both output and input-side amplifiers to galvanically isolate the circuits. The two sets of ICs allow the device to be connected to two independent ground voltage references on either side of the isolation barrier. The device uses DC-DC conversion to convert the voltage from the input side to the output side. A special safety feature of the device is that it can maintain a continuity and protection of the circuit during power supply failure or transients.
The primary function of the device is to ensure complete isolation between the primary and secondary circuits while allowing the control and power circuits to remain in capable communication with each other. This includes providing the necessary level of signal output to drive high-speed, high-current MOSFET and IGBT circuitry. The device also provides isolation against ESD, electrostatic discharge, to further protect the circuits.
Conclusion
The ADUM1402WSRWZ33 is a digital isolator with unique features, making it suitable for industrial applications such as motor drives, power converters, and LED lighting control. It employs a hybridization of an integrated transformer and two sets of ICs to achieve galvanic isolation while providing a optimized level of signal output for driving high-speed, high-current MOSFETs and IGBTs. It also has a safety feature to maintain continuity in the event of a power failure or transient.
