NCV5701ADR2G

Overview

The NCV5701ADR2G is a high-current IGBT gate driver from onsemi, designed for robust switching applications. It operates within a supply voltage range of 5.5 V to 35 V and delivers a peak 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 includes active Miller clamp functionality and DESAT protection with programmable delay. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C. Packaged in a compact SOIC-8 surface-mount format, it supports shutdown modes and maintains low quiescent current.

Feature Summary

• Integrates active Miller clamp to prevent false turn-on during high dv/dt events
• Includes DESAT protection circuitry with adjustable delay timing for short-circuit safeguarding
• Provides high peak source and sink currents for rapid IGBT switching transitions
• Features dedicated shutdown pin for precise control over driver state

Applications

• Industrial motor drives and inverters
• Switched-mode power supplies (SMPS)
• Automotive power electronics systems
• High-frequency AC/DC converters

Procurement Notes

Verify the specific suffix 'ADR2G' confirms the SOIC-8 package and tape-and-reel packaging format. Confirm AEC-Q100 automotive qualification status if required for your application. Ensure compatibility with the 5.5 V to 35 V supply range and check that the inverting logic aligns with your control signal requirements. Validate thermal performance within the specified operating temperature range.

Selection Notes

Select this component when high current drive capability is needed for IGBTs in a compact footprint. The integrated DESAT and Miller clamp features reduce external component count compared to basic drivers. Consider the inverting configuration requirement against your microcontroller or PWM controller outputs. Evaluate the 4 A peak current against the target IGBT's gate charge requirements at the intended switching frequency.

Part Context

This part belongs to the NCV5701 series of high-current gate drivers from onsemi. It is specifically engineered for demanding power conversion environments where reliability and fast switching are critical. The series emphasizes integration of protection features to enhance system safety without increasing board space significantly.

Replacement Considerations

Check datasheets for alternative parts offering similar 4 A output current and SOIC-8 packaging. Verify pinout compatibility and electrical parameter overlaps, particularly supply voltage ranges and propagation delays. Ensure any substitute also meets AEC-Q100 requirements if automotive qualification is necessary.
