Optocoupler Compatible Single-channel Isolated Gate Driver

NSi6801 is an isolated gate driver with single-channel optocoupler-compatible input, which can be used to drive IGBT, SiC and MOSFET. It can provide peak source/sink current of 5A/5A. It supports the minimum common mode transient immunity (CMTI) of 150kV/μs, which ensures the robustness of the system. The maximum power supply voltage of the driver is 32V. It has performance advantages over optocoupler gate drivers, including better reliability and aging performance, higher operation temperature, shorter propagation delay and less pulse width distortion. Therefore, NSi6801 is more suitable than photoelectric isolation driver in switching power supply systems, , photovoltaic inverters and motor drive systems which requires high reliability, high power density and high efficiency.
