IR2113-2

IR2113-2 Description

The IR2113-2 from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed for power MOSFET and IGBT applications. Housed in a 16-pin DIP (Through Hole) package, it operates within a 3.3V to 20V supply range, making it compatible with low-voltage logic circuits while driving high-side switches up to 600V bootstrap voltage. With dual independent channels, it delivers peak output currents of 2A (source/sink), ensuring robust switching performance. Although marked as obsolete, its legacy design remains relevant for industrial and automotive systems requiring reliable high-voltage isolation and fast switching (typ. 25ns rise / 17ns fall times).

IR2113-2 Features

• High-Side Voltage Support: Bootstrap capability up to 600V, enabling high-voltage applications.
• Fast Switching: Low propagation delays (25ns rise / 17ns fall) minimize power loss in high-frequency circuits.
• Dual Independent Channels: Flexible control for half-bridge or synchronous buck topologies.
• High Current Drive: 2A peak output current ensures quick turn-on/off of power switches.
• Wide Logic Compatibility: TTL/CMOS input thresholds (VIL=6V, VIH=9.5V) for easy interfacing.
• Robust Packaging: 16DIP through-hole for secure mounting in harsh environments.

IR2113-2 Applications

• Motor Drives: Ideal for 3-phase inverters in industrial BLDC/PMSM motor control.
• Switching Power Supplies: Used in high-voltage DC-DC converters and UPS systems.
• Automotive Systems: Suitable for electric vehicle (EV) powertrains and battery management.
• Industrial Inverters: Drives IGBTs/MOSFETs in welding equipment and solar inverters.

Conclusion of IR2113-2

The IR2113-2 excels in high-voltage, high-speed switching applications, offering low propagation delays, high current drive, and robust isolation. While obsolete, its proven reliability in motor drives, power supplies, and automotive systems makes it a legacy choice for designers needing a simple, high-performance gate driver.
