NCD57101DWR2G

Isolators - Gate Drivers Overview

The NCD57101DWR2G is a single-channel current-isolated gate driver from the NCD57100 series, manufactured by onsemi. It operates within a supply voltage range of 3.3 V to 5 V and delivers an output current of 7 A with a maximum output voltage of 32 V. The device features a propagation delay of up to 90 ns, with rise and fall times of 15 ns each. It provides 5 kVrms insulation voltage and functions reliably between -40°C and +125°C. Packaged in a SOIC-16 WB surface-mount format, it supports SiC technology and includes shutdown functionality.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation via current coupling for high-voltage switching applications
• Optimized for driving Silicon Carbide (SiC) power devices
• Features low propagation delay and symmetric rise/fall times for precise control

Isolators - Gate Drivers Applications

• Silicon Carbide (SiC) MOSFET gate driving
• High-frequency power conversion systems
• Industrial motor drives requiring isolated control

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DWR2G' against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system isolation requirements, specifically the 5 kVrms rating. Cross-reference pinout configurations for the SOIC-16 WB package to prevent integration errors during PCB layout and assembly processes.

Isolators - Gate Drivers Selection Notes

Select this component when driving SiC devices requiring high peak current and fast switching speeds. The 7 A output capability suits medium-power applications. Consider the 5 kVrms isolation barrier for safety-critical designs. Evaluate thermal performance given the 1.4 W power dissipation limit at elevated temperatures up to 125°C.

Isolators - Gate Drivers Part Context

This part belongs to the NCD57100 series of current-isolated gate drivers. Unlike capacitive or magnetic isolators, it uses digital current coupling for signal transmission. The series targets high-performance power electronics, offering robust isolation and fast transient response suitable for modern wide-bandgap semiconductor technologies.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the NCD57100 family, such as the NCD57001DWR2G, ensuring identical pinouts and electrical characteristics before substitution.
