IR2117STRPBF

Gate Driver Overview

The IR2117STRPBF is a single high-side gate driver IC designed for driving IGBTs and MOSFETs in high-voltage applications. It operates with a supply voltage range of 10 V to 20 V and supports floating operation up to 600 V. The device features non-inverting logic inputs compatible with CMOS and TTL standards. Key electrical parameters include a source current of 0.25 A and a sink current of 0.5 A. Propagation delays are specified at 125 ns for turn-on and 105 ns for turn-off. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +125°C.

Gate Driver Feature Summary

• Supports bootstrap operation for high-side switching without isolated power supplies
• Provides functional level shift isolation between logic and power grounds
• Features independent UVLO thresholds for both VCC and VBS supply rails

Gate Driver Applications

• Industrial motor control systems
• Solar inverter topologies
• High-voltage power supply circuits

Gate Driver Procurement Notes

Verify the specific suffix STRPBF confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the NRND status does not impact immediate production needs, as legacy components may have limited long-term availability. Ensure the ordering quantity aligns with the manufacturer's minimum reel size requirements to avoid additional handling fees or partial reel charges during procurement.

Gate Driver Selection Notes

Select this component when only a single high-side switch requires driving in a circuit design. The asymmetric drive currents suit applications where faster turn-off is prioritized over turn-on speed. Verify that the 600 V floating window matches the maximum bus voltage of the target power stage. Consider thermal dissipation capabilities within the SOIC-8 package if operating near maximum ambient temperatures.

Gate Driver Part Context

This part belongs to the IR2117 family of high-voltage gate drivers from Infineon Technologies. It serves as a specialized solution for high-side switching where traditional low-side drivers cannot provide the necessary potential shift. The STRPBF variant specifically denotes the surface-mount reel configuration, distinguishing it from through-hole or tube-packaged equivalents like the IR2117S.
