NCD57100DWR2G

Isolators - Gate Drivers Overview

The NCD57100DWR2G is a single-channel, galvanically isolated gate driver from onsemi, housed in a 16-pin SOIC-16WB package. It features capacitive coupling for signal transmission with an isolation voltage of 5 kVrms. The device supports a supply voltage range of 3.3 V to 5 V on the input side and drives loads up to 32 V on the output side. It delivers a peak output current of 7 A, with maximum propagation delays of 90 ns for both turn-on and turn-off states. Rise and fall times are specified at 15 ns each. It operates within a temperature range of -40°C to +125°C and includes a shutdown function.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology provides high common-mode transient immunity and electrical isolation between input and output circuits.
• Integrated shutdown pin allows for immediate disabling of the output to protect connected power devices.
• Single-channel configuration simplifies design for driving one IGBT or MOSFET switch.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Solar microinverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DWR2G' to ensure the correct tape-and-reel packaging and RoHS compliance status. Confirm that the SOIC-16WB footprint matches your PCB layout requirements. Check for automotive qualification if used in AEC-Q100 environments, as standard industrial versions may differ. Ensure compatibility with your control logic voltage levels before procurement.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with robust isolation is required for single-switch applications. The 7 A drive strength suits medium-power IGBTs and MOSFETs. Consider the 16-pin wide-body package for improved creepage distances compared to standard SOIC-8 options. Evaluate thermal performance under continuous load conditions given the 1.4 W power dissipation rating.

Isolators - Gate Drivers Part Context

This part belongs to the NCD57100 series of isolated gate drivers. It shares architectural similarities with other members like the NCD57101 but differs in specific pinout configurations or feature sets. The series targets efficient power conversion by replacing traditional magnetic transformers with compact capacitive isolation.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include the NCD57101DWR2G, which offers similar isolation and drive capabilities but may have different pin assignments or internal protection features. Verify functional equivalence regarding propagation delay and output current before swapping.
