Gate Driver Procurement Notes

Verify the obsolete status of the IR2117 before procurement, as it is no longer manufactured by Infineon Technologies. Confirm availability through authorized distributors or secondary markets. Ensure that any substitute components meet the required electrical specifications and pin compatibility. Check for RoHS compliance and specific packaging variants if applicable. Validate lead times and authenticity from reputable sources.

Gate Driver Selection Notes

Select this component for applications requiring a dedicated high-side driver with 600 V blocking capability. Consider the 0.25 A source and 0.5 A sink currents for driving medium-power switches. The 10 V to 20 V supply range suits standard logic-level interfaces. Evaluate the 125 ns and 105 ns propagation delays against switching frequency requirements. Ensure the 8-pin DIP package fits the mechanical constraints of the design.

Gate Driver Part Context

The IR2117 belongs to the IR211x family of gate drivers from Infineon Technologies (formerly International Rectifier). It is specifically engineered for high-voltage power switching applications. The device simplifies the drive circuitry for high-side N-channel MOSFETs and IGBTs by integrating level shifting and bootstrap functionality. It serves as a foundational component in power electronics designs requiring reliable high-side switching.

Gate Driver Replacement Considerations

The IR2117 is marked as obsolete. Direct substitutes include the IR2117PBF, which may be available from stockists. Verify functional equivalence and pinout compatibility when selecting alternatives.
