IR22141SS

IR22141SS is a full bridge gate driver designed to drive N-channel MOSFETs and IGBTs in a wide variety of applications. It provides an output current capacity of up to 2A and a peak output voltage of 35V, which makes it suitable for driving power switches up to 25A in high power industrial applications. The device integrates two channels of half-bridge gate drivers, and features a wide input voltage range of 5.5V to 22V, making it suitable for use in industry-standard 15V and 24V operating environments. Additionally, it has a built-in frequency adjustment range of up to 2MHz, so it can be used with a wide range of frequency-controlled switches, such as solenoids, motors, and laminated silicon power switches.

The IR22141SS gate driver provides a low-impedance control path between the PWM control signal and the power switch, ensuring fast and accurate switch control while protecting the inserted gate. This device also provides an adjustable dead time control function which allows the user to select an appropriate dead time and reduce the effects of shoot-through current in the bridge. This reduces the switching losses and allows the maximum efficiency of the bridge to be realized. An over-current fault protection function is integrated into the device, so that when an over-current fault occurs, the gate drive signal will automatically be shut off and the current will be shorted to ground.

In terms of features, the IR22141SS gate driver has robust EMC performance and a high operating temperature range, with an operating temperature range spanning from -40°C to 125°C. Additionally, it has a low noise level and an output short-circuit protection feature. It also has an integrated power-on reset and a soft start feature that improves the power supply response time and reduces inrush current and EMI. The gate driver is suitable for a wide range of power supply architectures, including automotive, DC-DC converter, and step-down transformer applications.

The typical application fields of IR22141SS gate driver include power supplies, switch mode power supplies, frequency switching, automation, and motor drive applications. The device is designed to handle high voltage and power levels, and it is also suitable for controlling large loads such as PWM-controlled motors and solenoids. Furthermore, the built-in over-current fault protection makes it suitable for power supply applications where short-circuit protection is required.

In terms of working principle, the IR22141SS gate driver is designed to be used with a PWM controller to provide the driving signal for the power switches in a bridge connection, such as an H-bridge arrangement. The PWM controller supplies the required control signal for the gate driver, which in turn provides the appropriate gate-voltage level for the power switches and ensures fast switching of the power switches. The device has two integrated channels, allowing for two half-bridge connections or a single full-bridge connection. The built-in frequency adjustability feature and adjustable dead time control allow the user to tune the device to meet the specific needs of the application. The integrated over-current fault protection will shut off the gate driving signal in the event of an over-current fault, thus protecting the device and connected power switches.

In conclusion, the IR22141SS gate driver is a high-performance, high-efficiency device designed to drive power switches in a wide range of power supply architectures and switch mode applications. The device integrates two channels of half-bridge gate drivers, and features a wide input voltage range, adjustable frequency range, adjustable dead time control, and built-in over-current fault protection. This device is suitable for controlling large loads such as PWM-controlled motors and solenoids, for use in power supplies, switch mode power supplies, frequency switching, automation, and motor drive applications.
