IR2301STR

Gate Driver Overview

The IR2301STR is a high-voltage, high-speed dual-channel gate driver IC designed for N-channel MOSFETs and IGBTs. It features independent high-side and low-side reference outputs with a bootstrap circuit. The device operates within a supply voltage range of 5 V to 20 V. Key electrical parameters include a peak output current of 200 mA (source) and 350 mA (sink). Propagation delays are specified at a maximum of 220 ns for turn-on and 200 ns for turn-off. The component supports junction temperatures up to 150°C and is housed in an 8-SOIC package.

Gate Driver Feature Summary

• Integrated bootstrap diode functionality for high-side drive
• High-voltage capability supporting up to 600 V bus voltages
• CMOS/TTL compatible logic inputs for direct microcontroller interfacing

Gate Driver Applications

• Motor control systems
• Power supply circuits
• Inverter topologies

Gate Driver Procurement Notes

Verify the specific suffix 'STR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Infineon documentation prior to integration. Ensure the design accounts for the non-inverting input logic configuration. Check for any end-of-life notices or obsolescence warnings associated with this specific part number variant before finalizing procurement plans.

Gate Driver Selection Notes

Select this component for applications requiring isolated high-side switching without external transformers. The SOIC-8 package offers a compact footprint for space-constrained designs. Consider the 600 V rating when selecting components for medium-voltage power stages. Verify that the 200 mA source current is sufficient for the target MOSFET or IGBT gate charge requirements at the intended switching frequency.

Gate Driver Part Context

This part belongs to the IR230x series of half-bridge drivers from Infineon Technologies. It serves as a bridge between low-voltage control logic and high-power switching devices. The STR suffix typically denotes reel packaging for automated assembly. It is functionally related to other variants like the IR2301S, differing primarily in packaging and manufacturing lot specifications.

Gate Driver Replacement Considerations

NCP5106ADR2G is listed as a similar alternative by distributors. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the replacement meets the same automotive or industrial qualification standards if required by the application.
