IRS25401PBF

Overview

The IRS25401PBF is a high-voltage half-bridge gate driver IC from Infineon Technologies, designed to drive external MOSFETs or IGBTs in half-bridge configurations. It operates with a supply voltage range of 8 V to 16.6 V and supports switching frequencies up to 500 kHz. The device features a robust output stage capable of delivering peak currents of 2 A source and 4 A sink. It includes integrated dead-time control, under-voltage lockout (UVLO), and thermal shutdown protection. Packaged in an 8-SOIC format, it ensures reliable performance across an operating temperature range of -25°C to +125°C.

Feature Summary

• Integrated half-bridge gate driver topology for high-side and low-side MOSFET/IGBT control
• Built-in dead-time management to prevent shoot-through conditions
• Comprehensive protection mechanisms including under-voltage lockout and thermal shutdown

Applications

• Universal AC-DC power supplies
• Induction heating systems
• Motor control applications

Procurement Notes

Verify component authenticity through authorized channels as the part may be discontinued. Confirm package integrity and moisture sensitivity level handling requirements prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Selection Notes

Select this component for applications requiring isolated half-bridge driving with integrated protection. Ensure input voltage stays within the 8 V to 16.6 V range. Consider thermal management due to SOIC packaging limitations in high-power scenarios.
