NCV5700DR2G

Overview

The NCV5700DR2G is a high-current, standalone IGBT gate driver manufactured by onsemi. It features a 16-pin SOIC package and supports both high-side and low-side configurations with an inverting logic input. The device delivers peak output currents of +4 A (source) and -6 A (sink). It operates within a supply voltage range of 12.5 V to 20 V and functions across a temperature range of -40°C to +125°C. Typical switching characteristics include a rise time of 9.2 ns and a fall time of 7.9 ns.

Feature Summary

• Integrated Active Miller Clamp to prevent spurious gate turn-on during high dv/dt events
• Built-in DESAT protection with programmable delay for short-circuit fault management
• Dedicated Enable (EN) input for independent driver control and system synchronization
• Accurate UVLO thresholds ensuring reliable bias supply monitoring and startup

Applications

• Solar inverters
• Motor control systems
• Uninterruptible power supplies (UPS)

Procurement Notes

Verify the specific suffix DR2G corresponds to the standard tape-and-reel packaging format required for automated assembly processes. Confirm that the NCV prefix indicates compliance with automotive quality standards, including AEC-Q100 qualification and PPAP capability, if the application demands such reliability specifications. Ensure the ordering part number matches the exact pinout and thermal requirements of the target PCB design.

Selection Notes

Select this component when a single-channel, non-isolated high-current drive solution is required for IGBTs. The inverting configuration simplifies logic interfacing from digital isolators or optocouplers. Consider the 16-pin SOIC footprint for board space constraints. The integrated protection features reduce external component count compared to discrete driver solutions, offering a cost-effective approach for medium-power industrial applications.

Part Context

This device belongs to the NCV5700 series of high-performance IGBT drivers designed for robust operation in harsh environments. The NCV prefix signifies that the part meets stringent automotive and industrial site-specific requirements. It serves as a standalone driver, distinct from isolated variants like the NCV57001, relying on external isolation components if galvanic isolation is necessary for the control circuitry.

Replacement Considerations

• NCD5700DR2G
• NCV5700BDR2G

FAQ

Does the NCV5700DR2G provide galvanic isolation?

No, the NCV5700DR2G is a standalone, non-isolated gate driver. Galvanic isolation must be achieved using external components such as digital isolators, optocouplers, or pulse transformers.

What is the function of the EN pin?

The EN (Enable) pin allows for independent control of the driver. Activating this pin enables the gate drive output, while deactivating it disables the output, providing a method for system-level shutdown or synchronization.
