Isolators - Gate Drivers

The CPC3140GSTR is a member of a growing family of single-channel, micropower isolator gate drivers for use in industrial, medical, consumer and automotive applications. It is a complete step-down DC/DC converter featuring overload protection, galvanic isolation, and a highly efficient design.

CPC3140GSTR Application Field

The CPC3140GSTR is designed to drive the gates of external MOSFETs, IGBTs, or H-Bridges in automotive, industrial, and consumer applications including audio amplifiers, power supplies, LED dimming, motor drives, HVAC systems, and many more. Its input voltage and output current range allows the CPC3140GSTR to be used in applications with a wide variety of input and output voltage and current requirements. The device can also be used with a wide variety of sensors including resistive, capacitive, photodiode, and thermocouple sensors.

CPC3140GSTR Working Principle

The CPC3140GSTR isolator gate driver uses a small off-the-shelf transistor as the isolation element. It works by passing a “common-mode” signal through the transistor from one side of the isolation to the other. This eliminates the need for bulky switching transistors, increasing efficiency and allowing for high-speed operation. On the input side of the device, a precision voltage regulator circuit is used to bring the input voltage within a given range. The output (gate driver output) is controlled by various control signals which are at either a logical high or low. The CPC3140GSTR is also capable of driving external gates up to 35 Amps.

The CPC3140GSTR is designed to be robust and reliable in operation, ensuring years of reliable, error-free performance. It also provides protection against power supply overvoltage, overcurrent, and undervoltage conditions. The device also offers short circuit protection to the external host, and over-temperature protection. The design also incorporates a built-in current limit that will limit the peak output current to a safe value should an over current condition occur.

Conclusion

The CPC3140GSTR isolator gate driver is a highly efficient, reliable, and cost-effective method for driving external MOSFETs, IGBTs, or H-Bridges. Its micropower design makes it suitable for a wide range of automotive, industrial and consumer applications. Its overload protection, galvanic isolation, and highly efficient design make it an excellent choice for design engineers.
