Single-Channel IsolatedSmart GateDriver

Part Number: NSi66x1A


NSi6611 is a sophisticated single-channel smart isolated gate driver meticulously crafted to empower a variety of applications by controlling IGBTs, power MOSFETs, SiC MOSFETs, and other potent transistors. Its primary role extends beyond control—it serves as a safeguard, ensuring the secure operation of these components.

What sets the NSi6611 apart are its capabilities: it can independently regulate the rising and falling durations with separate outputs. It boasts rail-to-rail output support, providing an impressive source and sink current capability of up to 10A/10A. Furthermore, the NSi6611 boasts an array of protective functions including UVLO, Miller clamp, DESAT protection, and soft shutdown. In case of faults like short circuits or undervoltage, a dedicated pin indicates the occurrence.

Notably, the NSi6611 is equipped with ASC function, enabling it to forcibly set the output to a high state during emergencies. Its robustness is fortified by a minimum common mode transient immunity (CMTI) of 150kV/μs, enhancing system stability.

On the voltage front, the driver side supports a maximum supply voltage of 32V, while the input side accommodates supply voltages within the range of 3V to 5.5V. The NSi6611 stands out with its considerable drive current, expansive power supply voltage range, and remarkable CMTI performance. Excellently designed for protection, it finds its ideal niche in switching power supply systems and inverters that demand a trifecta of qualities: reliability, power density, and efficiency.
