NCD5700DR2G

Overview

The NCD5700DR2G is a high-current IGBT gate driver manufactured by onsemi, designed for robust power switching applications. It features a single-channel configuration housed in a 16-SOIC surface-mount package. The device supports both high-side and low-side driving capabilities with synchronous channel operation. Key electrical parameters include a peak output current of 7.8A sourcing and 6.8A sinking. Logic input thresholds are defined at 0.75V for VIL and 4.3V for VIH. Typical switching performance includes rise and fall times of 9.2ns and 7.9ns respectively. The component operates within a temperature range of -40°C to 125°C and utilizes an inverting input type.

Feature Summary

• Integrated high-side and low-side drive capability for flexible half-bridge configurations
• High peak output current capacity supporting rapid IGBT switching transitions
• Active Miller clamp functionality to prevent unintended turn-on during fast dv/dt events
• Comprehensive protection features including under-voltage lockout and desaturation detection

Applications

• Industrial motor drives and inverters
• Switched-mode power supplies (SMPS)
• Welding equipment power stages
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix DR2G corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB layout dimensions. Ensure design compatibility with the specified logic voltage levels and operating temperature range before finalizing procurement orders.

Selection Notes

Select this component when high peak current drive is necessary for large IGBT modules requiring fast switching speeds. The integrated desaturation protection simplifies circuit design compared to discrete solutions. Consider the 16-pin package size relative to board space constraints. Verify that the inverting logic interface aligns with the control signal polarity of the upstream microcontroller or driver stage.

Part Context

This part belongs to the NCD5700 series of high-current IGBT gate drivers from onsemi. The series focuses on providing reliable switching performance for industrial power electronics. The non-isolated variant distinguishes itself from the galvanically isolated counterparts in the same family, offering a cost-effective solution for applications where isolation is handled externally or not required.

Replacement Considerations

NCD5700DWR2G offers similar high-current specifications but may differ in pinout or feature set; verify datasheet compatibility. NCV5700 serves as a qualified automotive-grade alternative within the same functional family. Cross-reference pin assignments and electrical limits carefully before substitution.
