Working Principles

The IRS2548DSTRPBF is a high voltage, high frequency power MOSFET driver IC. It provides the necessary control signals to drive power MOSFETs in various applications such as switch-mode power supplies, motor drives, and lighting systems. The IC utilizes level shifting techniques to efficiently drive the high-side and low-side MOSFETs, ensuring fast switching and minimal power losses.

The integrated bootstrap diode simplifies the high-side gate drive circuitry by eliminating the need for an external diode. Undervoltage lockout protection ensures that the IC operates within safe voltage levels, preventing damage to the MOSFETs. Overcurrent protection and shoot-through prevention logic further enhance the reliability of the system.

The adjustable dead-time control allows fine-tuning of the time delay between the high-side and low-side gate signals, preventing any potential short-circuits during switching transitions. The fault reporting output provides feedback on any detected faults, enabling timely troubleshooting and system shutdown if necessary. Thermal shutdown protection safeguards the IC from excessive temperature, preventing thermal damage.
