Smart Isolated Gate Driver
NSI6611 is a single-channel smart isolated gate driver designed to drive IGBT, power MOSFET and SiC MOSFET and other power transistors in many applications and provide protection for their safe operation. It can provide separate output to control the rising and falling duration respectively, it supports rail-to-rail output, and can provide a maximum 10A/10A source and sink current capability. NSI6611 can provide protection functions, such as UVLO, Miller clamp, DESAT protection, soft shutdown, and when short circuit fault or undervoltage occurs, the fault can be indicated through a separate pin. NSI6611 supports ASC function and can be used to force the output to be high in emergency situations. It supports minimum common mode transient immunity (CMTI) of 150kV/μs to improve system robustness. The maximum supply voltage of driver side is 32V, and the input side accepts supply voltages from 3V to 5.5V. NSI6611 features large drive current, wide power supply voltage range, and high CMTI, and is designed with excellent protection. It is suitable for switching power supply systems and inverters which require high reliability, high power density and high efficiency.
