IR2104S

Gate Driver Overview

The IR2104S is a 600 V half-bridge gate driver IC designed for driving IGBTs and MOSFETs. It features junction isolation with functional level-shift technology, enabling high-side switching in floating configurations. The device operates within an input supply range of 10 V to 20 V. Key electrical parameters include a source output current of 0.21 A and a sink output current of 0.36 A. Propagation delays are specified at 680 ns for turn-on and 150 ns for turn-off. Under-voltage lockout thresholds are set at 8.9 V (On) and 8.2 V (Off). The component supports industrial quality standards and operates across a junction temperature range of -40°C to 150°C.

Gate Driver Feature Summary

• Integrated high-side bootstrap driver capability for floating half-bridge topologies
• Junction isolation providing functional level-shift for high-voltage applications
• Built-in under-voltage lockout protection for both supply rails

Gate Driver Applications

• Industrial motor control systems
• Switched-mode power supplies
• Inverter circuits for AC drives

Gate Driver Procurement Notes

Verify the specific suffix designation against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Cross-reference lead times and RoHS compliance status directly with authorized distributors or the manufacturer's ordering portal prior to procurement.

Gate Driver Selection Notes

Select this component when a robust half-bridge solution with integrated high-side drive is required for voltages up to 600 V. Consider the 0.21 A source current limit when sizing bootstrap capacitors for high-frequency operation. Verify that the load capacitance and switching frequency requirements align with the specified propagation delays and rise/fall times to ensure stable performance.

Gate Driver Part Context

This part belongs to the IR210x series of high-voltage gate drivers from Infineon Technologies. It shares architectural similarities with the IR2104 but may differ in packaging or specific qualification grades. The series is widely utilized in power electronics requiring reliable isolation between low-voltage control logic and high-voltage power stages.

Gate Driver Replacement Considerations

The IR2104 is a closely related variant within the same product family. Verify pin-to-pin compatibility and check if the specific suffix indicates differences in packaging or environmental certification before substitution.
