IR2117

IR2117 Description

The IR2117 from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for driving MOSFETs and IGBTs in high-side configurations. This single-channel driver operates with a supply voltage range of 10V to 20V and supports bootstrap operation up to 600V, making it suitable for high-voltage switching applications. The device is housed in an 8-pin DIP (Through Hole) package and is classified as obsolete, though it remains relevant for legacy designs. With a peak output current capability of 250mA (source) and 500mA (sink), it ensures robust switching performance. The rise and fall times are typically 80ns and 40ns, respectively, enabling efficient high-frequency operation.

IR2117 Features

• High-Side Voltage Capability: Supports up to 600V bootstrap voltage, ideal for driving high-side switches in half-bridge or full-bridge topologies.
• Fast Switching: 80ns rise time and 40ns fall time minimize switching losses, enhancing efficiency in power conversion systems.
• High Current Drive: 250mA source / 500mA sink current ensures reliable gate drive for power switches.
• Wide Supply Range: Operates from 10V to 20V, compatible with standard logic levels (VIL = 6V, VIH = 9.5V).
• Robust Packaging: 8DIP through-hole package provides mechanical durability and ease of prototyping.
• Obsolete but Reliable: While no longer in production, it remains a trusted choice for maintenance and legacy systems.

IR2117 Applications

The IR2117 is particularly suited for:

• Motor Drives: Efficiently controls high-side switches in BLDC and PMSM motor drives.
• Switched-Mode Power Supplies (SMPS): Enables fast switching in AC-DC and DC-DC converters.
• Inverters: Used in solar inverters and UPS systems for high-voltage switching.
• Industrial Power Systems: Ideal for half-bridge and full-bridge configurations in industrial automation.
• Legacy Designs: Maintains compatibility with older systems requiring high-voltage gate drivers.

Conclusion of IR2117

The IR2117 is a high-performance gate driver offering robust high-side switching capabilities, fast transition times, and reliable operation in demanding power electronics applications. While marked as obsolete, its 600V bootstrap capability, high current drive, and wide voltage range make it a preferred choice for legacy designs and specific high-voltage applications. Engineers working on motor drives, inverters, and industrial power systems may still find this IC valuable for its proven performance and durability.
