The IR2103SPBF is an IC (integrated circuit) component manufactured by Infineon Technologies, designed specifically for high-speed power MOSFET and IGBT (Insulated Gate Bipolar Transistor) drivers. It is widely used in various applications such as motor drives, switch-mode power supplies, and class D audio amplifiers.
Here are some key features of the IR2103SPBF:
1. High and Low-Side Gate Driver: The IC offers independent high-side and low-side referenced outputs, allowing it to drive power MOSFETs and IGBTs efficiently. This dual channel architecture ensures effective switching and minimal power losses.
2. Bootstrap Circuitry: The IC incorporates bootstrap circuitry, which eliminates the need for an external level-shifter circuit. This simplifies the overall design and reduces component count, making it more cost-effective.
3. Gate Drive Supply Range: IR2103SPBF operates with a wide gate drive supply range of 10V to 20V, allowing flexibility in voltage supply selection and compatibility with various power devices.
4. Propagation Delay Matching: The IC ensures precise control by providing a tight match between the high-side and low-side gate driver propagation delays. This feature minimizes the chance of cross-conduction and improves system performance.
5. Logic Inputs: The IC accepts logic inputs compatible with microcontrollers and other digital logic circuits. Its logic inputs are compatible with both 3
