Isolators are a critical component for success in the development of efficient, cost-effective products. Specifically, Gate Drivers, isolators designed to drive an FET Gate output, enable electronic systems to identify and respond quickly to incoming signals and/or commands without the need for current-limiting components. One example of such isolator is UCC21520DW, which is designed to enable rapid and efficient communications between process control systems and digital and analog transducers for a wide range of application fields.

UCC21520DW Application Field

The UCC21520DW can be used in a wide range of applications. Commonly they are used for the following:

• Industrial automation applications.
• Medical technology.
• Industrial control systems.
• Motion control systems.
• Automotive engine control.

These Gate Drivers are ideal for any application field that requires rapid and reliable signal discrimination and conversion.

UCC21520DW Working Principle

The UCC21520DW isolator uses a two-stage process to convert signals from an input to an output. The first stage is the digital signal discrimination stage where the incoming signal is identified as either a high or a low. This information is then stored in memory and is used in the second stage, the voltage translation stage.

The voltage translation stage uses the incoming signal as the reference voltage. This reference voltage is then compared with a pre-determined voltage and if the detected voltage is higher than the predetermined voltage, the output is interpreted as a high signal and a low signal if it is lower. This two-stage process enables ultra-fast signal discrimination and helps eliminate the need for current-limiting components.

The UCC21520DW isolator is designed for reliable and efficient operation in a wide range of temperature ranges. It is capable of operating in temperature ranges from -40°C up to 85°C and is fully protected against electrostatic discharge.

Conclusion

The UCC21520DW is a perfect example of how isolators and Gate Drivers can provide efficient and reliable communication between process control systems and digital and analog transducers. Offering rapid signal discrimination and low temperature operation, it can easily be integrated into a wide range of application fields including industrial automation applications, medical technology, industrial control systems, motion control systems, and automotive engine control.
