The IR2111STR is an IC (Integrated Circuit) component manufactured by Infineon Technologies. It is a high-voltage, high-speed power MOSFET and IGBT driver optimized for driving middle and high power applications such as motor control, power supplies, and inverters. This IC offers several key features that make it suitable for various industrial and consumer electronics applications.
One of the noteworthy features of the IR2111STR is its ability to provide independent high and low side referenced output channels. It has two outputs, one called "LO" (Low) and the other called "HO" (High). These channels ensure the reliable, simultaneous switching of both the low-side and high-side power switches, thereby minimizing any potential delays or timing issues.
This IC supports a wide input voltage range, enabling it to operate with different system voltages. It can handle input voltage levels from 10 V to 20 V, making it versatile for various power supply designs. Additionally, the IR2111STR has an undervoltage lockout (UVLO) feature that ensures a well-controlled start-up and shutdown by monitoring the input voltage. This prevents any unwanted or unstable operation during power supply fluctuations.
An essential characteristic of the IR2111STR is its strong power MOSFET and IGBT driving capability. It can deliver high peak currents of up to 2 A in both source and sink modes
