The IR2214SS is a part of the family of voltage-mode shielded-gate drivers from International Rectifier (IR), which were designed specifically to protect against short circuit, input overvoltage, leakage, and output short circuit, among other disruptions and faults. The IR2214SS belongs to general-purpose isolated and/or non-isolated circuit configurations, and it is a specific type of logic-input/output power transistor device. An isolated version will couple isolated supplies and/or provide isolated output stages, while a non-isolated version will couple non-isolated supplies and/or provide non-isolated outputs, such as in USB PC applications.

The IR2214SS was designed for high-current and high-voltage switching applications, and it can help create superior drive and greater performance due to its optimized structure and high-frequency power switching. This driver is also optimized for low output offset and will provide very low input and offset voltages, which are key features for handling power supplies and high power loads. This driver is a robust and reliable device for high-end safety and reliability across many applications and processes.

IR2214SS can be used in many applications, including in industrial control, automotive, aerospace, telecommunications, defense, computer peripherals, and more. For example, it can be used in automotive powertrain applications such as fuel injectors, EGR valves, transmission control, climate control, and powertrain control modules. It can also be used in aerospace system applications such as flight control systems, wing flap actuation systems, and landing gear actuation systems.

The working principle of the IR2214SS also lies in its shielding feature. When an abrupt voltage change is detected in a sensing circuit, this device will shut off the output stage, thereby protecting the circuit from high-voltage spikes. The high-side and low-side drivers also have a data-level shield that works to reduce the noise in the data lines, which enhances the accuracy of the sensing and switching process.

The IR2214SS utilizes shielded-gate drivers that reduce the cross-coupled noise, consequentially reducing current leakage. This technology helps reduce electrical interference and ensures that the safety of the application and equipment remains intact. The shield-gate also works to reduce the need for additional external current sensing components by using a gate-source voltage drop to determine the current passing through the device.

In addition, this device also incorporates internal "quiet cells" to reduce electromagnetic interference (EMI) such as radio frequency noise (RFI), and a narrow-burst off-mode that helps provide the system low average power dissipation. The IR2214SS also includes Safety and Performance Advantages (SPA), which will significantly reduce the cost of production while ensuring reliability and safety of the system.

The IR2214SS offers several technical advantages. It runs at up to 300V, at 600mA for pulse currents, with a maximum frequency of 350 kHz, and it is designed for use with logic signals between 4.2V and 5.5V. It is also designed for low input and output offset voltage, low power dissipation, and thermal shut-down. This device is a reliable and efficient gate driver for many switching applications, and it can be used for both isolated and non-isolated power stages.

The IR2214SS is an excellent choice for electronic applications because of its high-frequency power switching and superior NOE protection features. It has been designed to be a robust and reliable part, and it can help to reduce costs while improving the safety and reliability of the systems pressure sensitive applications, such as automotive and aerospace systems. This device can also be used in industrial control, telecommunications, computers, and other high-end safety and reliability processes.
