IR2110STR

Gate Driver Overview

The IR2110STR is a high-voltage, high-speed power MOSFET and IGBT driver featuring independent high-side and low-side referenced output channels. It incorporates a floating channel designed for bootstrap operation to drive N-channel devices in high-side configurations. The component supports an input supply voltage range of 10 V to 20 V and provides peak source and sink currents of 2.5 A each. It utilizes functional level shift junction isolation and includes shutdown functionality with specified UVLO thresholds at 8.2 V (Off) and 8.5 V (On).

• High-frequency switching applications requiring matched propagation delays.
• Class-D audio amplifier output stages.

Gate Driver Procurement Notes

Verify the specific manufacturer designation associated with the IR2110STR part number, as this prefix may indicate a third-party fabrication or distributor-specific marking rather than the original design owner. Confirm that the device meets the required industrial quality grade and RoHS compliance standards through official datasheets. Ensure the ordering suffix aligns with the desired package type and tape-and-reel specifications before finalizing procurement.

Gate Driver Selection Notes

Select this component when designing circuits requiring isolated high-side switching capabilities for N-channel power devices. Consider the 500 V voltage rating and 2.5 A output current capability against the load requirements. Evaluate the propagation delay characteristics for timing-sensitive applications. Verify compatibility with the system's logic input levels and ensure adequate decoupling for the VCC and bootstrap capacitors.

Gate Driver Part Context

This device belongs to a family of high-voltage gate drivers intended for bridging applications. It serves as a critical interface between low-voltage control logic and high-power switching elements. The design emphasizes speed and reliability for demanding power electronics environments, supporting both half-bridge and full-bridge configurations commonly found in modern power conversion systems.
