NCP51561BADWR2G

NCP51561BADWR2G Description

The NCP51561BADWR2G from onsemi is a high-performance, dual-channel digital isolator with integrated gate driver functionality, designed for demanding power electronics applications. It features 5kVrms isolation (certified by CQC, UL, and VDE) and utilizes capacitive coupling technology for robust noise immunity. With a wide output supply voltage range of 18.5V to 30V, this device supports high-side and low-side gate driving in half-bridge or full-bridge configurations. Its ultra-fast propagation delay (max 58ns) and low pulse width distortion (<5ns) ensure precise switching control, critical for high-frequency power converters.

NCP51561BADWR2G Features

• High-Speed Switching: Rise/fall times of 11ns/10ns and peak output currents of 9A (source) / 4.5A (sink) enable efficient driving of MOSFETs/IGBTs.
• Superior Noise Immunity: 200V/ns common-mode transient immunity (CMTI) ensures reliable operation in noisy environments.
• Dual-Channel Isolation: Two independent channels with 5kVrms isolation, ideal for bidirectional or redundant systems.
• Robust Packaging: 16-pin SOIC surface-mount package with MSL 1 (unlimited) rating, suitable for automated assembly.
