IR2304SPBF

Gate Driver Overview

The IR2304SPBF is a half-bridge gate driver IC designed for driving IGBTs and MOSFETs. It operates with a supply voltage range of 10 V to 20 V and supports a maximum voltage rating of 600 V. The device provides an output source current of 78 mA and a sink current of 169 mA. Propagation delays are specified at 220 ns for both turn-on and turn-off states. It utilizes junction isolation and features undervoltage lockout thresholds of 8.9 V (on) and 8.2 V (off).

Gate Driver Feature Summary

• Integrated shoot-through protection mechanism to prevent simultaneous conduction in half-bridge configurations.
• Functional level shift capability allowing high-side switching up to 600 V using junction isolation.
• Undervoltage lockout protection ensures reliable operation by monitoring VCC and VBS supply levels.

Gate Driver Applications

• Driving IGBTs in motor control applications
• Gate driving for power MOSFETs in industrial inverters
• Half-bridge converter stages in power supplies

Gate Driver Procurement Notes

Verify the specific suffix 'SPBF' against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Check the component lifecycle status, as some listings indicate end-of-life or not-recommended-for-new-design classifications. Ensure the ordering part number matches the required lead frame finish and tape/reel or tube packaging specifications defined in the official Infineon documentation.

Gate Driver Selection Notes

Select this component when a half-bridge topology with moderate drive strength is required. The 78 mA source and 169 mA sink currents suit medium-power MOSFETs and IGBTs. Consider the 220 ns propagation delay for switching frequency requirements. Verify that the 10 V minimum VCC requirement aligns with the control logic interface. Ensure the SOIC-8 package fits the thermal and spatial constraints of the design.

Gate Driver Part Context

The IR2304SPBF belongs to the IR230x series of high-voltage gate drivers from Infineon Technologies. It is part of a family of monolithic integrated circuits designed for hard-switching applications. The SPBF suffix typically denotes a Pb-free (RoHS compliant) variant in the SOIC-8 package. This component serves as a bridge between low-voltage control logic and high-voltage power switches.
