IR21593

Lighting, Ballast Controllers Overview

The IR21593 is a high-voltage, high-speed power MOSFET and IGBT driver provided by Infineon Technologies. It is designed to drive both N-channel power MOSFETs and N-channel IGBTs in low and high-side configurations or as a half-bridge topology. The device features a bootstrap supply for the high-side driver and a separate supply for the low-side driver. It includes logic-compatible inputs, a shutdown input, and output protection features such as desaturation detection and under-voltage lockout (UVLO) for both supply rails. The component operates within specified voltage ranges and temperature limits suitable for industrial applications.

Lighting, Ballast Controllers Feature Summary

• Inverter circuits

Lighting, Ballast Controllers Procurement Notes

Verify the exact suffix and package type against the official Infineon datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the specific variant matches the required pin configuration and thermal characteristics for the target PCB layout.

Lighting, Ballast Controllers Selection Notes

Select this driver for applications requiring robust gate driving of high-power switches with integrated fault protection. Consider the operating voltage range and current drive capabilities relative to the connected MOSFET or IGBT gate charge. Evaluate the need for desaturation protection and UVLO features based on system safety requirements.

Lighting, Ballast Controllers Part Context

This component belongs to the family of high-voltage gate driver ICs from Infineon Technologies. These drivers are engineered for reliable operation in harsh electrical environments, providing isolated level shifting and sufficient current to switch power devices efficiently. They are commonly used in power electronics where precise control and protection of high-side switches are critical.

Lighting, Ballast Controllers Replacement Considerations

Check for direct pin-to-pin replacements within the same Infineon product line that may offer updated features or availability. Verify compatibility with existing circuit designs, including voltage ratings and drive currents, when substituting with other manufacturers' components.
