Optocoupler-compatible Smart Isolated Gate Driver
NSi68515 is an optocoupler-compatible single-channel smart isolated gate driver designed to drive and provide protection for safe operation of IGBTs, power MOSFETs and SiC MOSFETs in many applications. NSi68515 can provide up to +5A/-5A source/sink current capability, with a maximum power supply voltage of 32V on the driver side and a power supply voltage of 3V to 5.5V on the input side. It can provide excellent protection function, such as UVLO, Miller clamp, DESAT protection, and soft shutdown, etc., and send alarm by a separate pin when detecting a short circuit fault or undervoltage. It is available in automatic alarm reset version, rail to rail output version and non-rail to rail output version. It supports a minimum common-mode transient immunity (CMTI) of 150kV/μs to improve system robustness. NSi68515 features high driver current, wide range of power supply voltage, high CMTI, and has excellent protection function, which is suitable for motor drive, inverter,
switching power system and other systems with high reliability, high power density and high efficiency.
