IR2113-1

IR2113-1 Description

The IR2113-1 from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed for power MOSFET and IGBT control in demanding applications. Housed in a 14-pin DIP (Through Hole) package, it operates over a 3.3V to 20V supply range, making it compatible with both low-voltage logic and higher drive requirements. With independent high- and low-side driver channels, it supports bootstrap operation up to 600V, enabling efficient high-side switching without an isolated power supply. The device delivers peak output currents of 2A (source/sink), ensuring robust gate drive for fast-switching power devices.

IR2113-1 Features

• High-Speed Switching: Features 25ns rise and 17ns fall times (typical), minimizing switching losses in high-frequency applications.
• Wide Voltage Range: Compatible with 3.3V logic inputs (VIL/VIH: 6V/9.5V) and supports bootstrap operation up to 600V.
• High Current Drive: 2A source/sink capability ensures rapid turn-on/off of power devices, reducing thermal stress.
• Robust Design: REACH unaffected and MSL 1 (Unlimited) rated, suitable for industrial environments.
• Independent Channels: Enables flexible half-bridge or low-side configurations.

IR2113-1 Applications

The IR2113-1 excels in:

• Motor Drives: Ideal for brushless DC (BLDC) and stepper motor controllers due to its high-speed switching and bootstrap capability.
• Switching Power Supplies: Used in AC-DC converters, inverters, and PFC circuits for efficient high-voltage switching.
• Industrial Systems: Suitable for UPS, welding equipment, and induction heating where reliable high-voltage isolation is critical.
• Renewable Energy: Integrates into solar inverters and wind turbine converters for robust power management.

Conclusion of IR2113-1

The IR2113-1 is a versatile, high-performance gate driver offering fast switching, high voltage tolerance, and robust drive strength. While now obsolete, its legacy design remains relevant for applications requiring high-side drive without isolated supplies. Engineers favor it for its simplicity, reliability, and compatibility with diverse power topologies, making it a historical benchmark in half-bridge gate drivers. For modern alternatives, Infineon’s newer gate driver families may be considered.
