IR2107STR is one of the gate drivers in PMIC (Power Management Integrated Circuit). It is a low-side and high-side gate driver, which is suitable for most applications requiring a gate driver in the downstream line.

With the help of a number of device technologies, the working principle of IR2107STR is able to offer high performance and reliability. Firstly, the High-Side Pole Sense technology offers an improved, adjustable, robust and low-cost solution for high-side switching, making it especially suitable for widely used applications, such as bootstrap power supply. Secondly, the Fast Transient Response circuitry provides better transient response on all loads, thus ensuring that the gate driver will respond in an accurate and rapid manner to any changes in the load current, voltage or power conditions. Thirdly, the under-voltage lockout (UVLO) system restricts the operation of the driver in the event of a fault or over-current condition. Fourthly, the adjustable low-side slew rate control provides easy modification of the low-side edge rate, allowing safer and more efficient power switching.

With these features, IR2107STR is suitable for a variety of applications, such as speed control, HVAC, industrial motion control and automotive systems, e.g. low-side switch, low-side driver and high-side driver. In each of these applications, the high-side, low-side and bootstrap poles of the device are able to control the flow of power between different components in a circuit, such as a motor, a capacitor, a voltage regulator or an LED. In addition, the IR2107STR is able to provide power isolated from ground and thus enable isolated power supply.

The IR2107STR includes a unique input capability to load the power switch side of the driver. This feature allows the device to sense the internal inductive load on the device and adjust the output slew rate accordingly. The result is faster rise and fall times, providing improved energy efficiency and quieter operation. The overload protection also helps with protecting the device against current overloading.

In addition, the device offers an adjustable protection circuitry with adjustable trip points. This feature allows the user to adjust the protection thresholds of the device, ensuring that the device will shut down before it reaches its maximum threshold or cause any damage.

The IR2107STR is also designed to be a low-EMI (electromagnetic interference) device, thus preventing potential interference from other electronic devices. The integrated high-side power circuit offers a significant EMI improvement compared to traditional drivers, helping to reduce the electromagnetic interference of the system and resulting in better overall performance.

Overall, the IR2107STR is a powerful and highly versatile gate driver, offering excellent performance and reliability for a wide range of applications. It is suitable for high-side, low-side, bootstrap and low-side switching, as well as for low-EMI gate drivers for automotive, HVAC and industrial motion control applications.
