Cost-effective Optocoupler Compatible Single-Channel Isolated Gate Driver
NSI6801x series is the second generation product based on NSi6801, including NSI68010B and NSI68011C. NSI6801x is more cost-effective compared with the first generation in order to assist customers to reduce system costs and increase efficiency. NSI6801x single-channel isolated gate driver can be pin compatible with optically coupled gate drivers. It can provide up to 2A drive current. The minimum common mode transient immunity (CMTI) of 150kV/μs ensures system robustness. The maximum supply voltage of the driver is 32 V. When the input circuit is applied in an optocoupler-compatible system, it offers better performance compared with optocoupler gate drivers, including better reliability, longer working life, higher operating temperature, shorter propagation delay and less pulse width distortion. Therefore, NSI6801x is suitable for replacing opto-isolated drivers in switching power supply systems which require high reliability, power density and efficiency.
