NCD5701ADR2G

Overview

The NCD5701ADR2G is a high-current IGBT gate driver manufactured by onsemi, designed for robust switching applications. It operates within a supply voltage range of 5.5 V to 35 V and delivers an output current of 4 A. The device features an inverting configuration with propagation delays up to 70 ns, rise times of 9.2 ns, and fall times of 7.9 ns. It functions reliably across an extended temperature range from -40 °C to +125 °C. Packaged in an SOIC-8 surface-mount format, it includes active Miller clamp and DESAT protection with programmable delay capabilities.

Feature Summary

• Integrates active Miller clamp functionality to prevent false turn-on events during high dv/dt switching conditions.
• Includes DESAT protection circuitry with programmable delay to safeguard IGBTs against short-circuit faults.
• Provides high peak output current capability suitable for driving large power modules efficiently.

Applications

• Industrial motor drives
• Switched-mode power supplies
• Inverter circuits

Procurement Notes

Verify the specific suffix 'ADR2G' corresponds to the required tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact electrical specifications and package type required for the design. Cross-reference datasheet revisions to confirm feature consistency.

Selection Notes

Select this component when a single-channel, inverting gate driver with integrated fault protection is required. It is suitable for designs needing moderate drive strength with built-in desaturation monitoring. Consider thermal dissipation limits and ensure adequate PCB layout for high-current paths. Verify compatibility with control logic levels due to the inverting signal path.

Part Context

This device belongs to the NCD5701 series of high-current IGBT gate drivers from onsemi. The series focuses on providing reliable protection and fast switching performance for industrial power electronics. The NCD5701ADR2G variant specifically denotes the automotive-grade or enhanced reliability version packaged in SOIC-8.

Replacement Considerations

Direct substitutes include NCD5701A and NCD5701. Verify pinout compatibility and electrical parameter alignment before substitution. Check if alternative packages are available for the same functional core.
