The SI8286BC-ISR is a Isolators - Gate Drivers, specifically designed to secure an isolated and reliable gate drive solution for two N-channel Power MOSFETs, IGBTs, or BJTs in high side and low side configurations. It offers safety isolation while achieving low propagation delays, low switch-off time, and high efficiency. In addition, this IC has integrated fault protection with wide power supply voltage range and international certifications, making it suitable for various power converters.

Application Field

The SI8286BC-ISR is suitable for different applications such as single phase to three phase, AC/DC, DC/DC, DC/AC, etc. Its isolation voltage of up to 5000Vrms makes it an optimal choice for high power circuits. Furthermore, drives with low RDS(ON) and very low turn-on capability work well with this driver. It can also be used for automotive applications due to the high temperature ratings. This driver is also adopted for applications in medical instruments, motor drive systems, and industrial automation products.

Working Principle

The SI8286BC-ISR uses an isolated capacitive DC/DC converter to generate a well-isolated high side and low side gate drive from a DC input. The isolated driving capabilities reduce the propagation delay and minimize device interaction. This driver features a wide, adjustable dead time that eliminates shoot-through current between components and maximizes power conversion efficiency and reliability. Its internal bootstrap diode clamps the output voltage within the trip levels, and its built-in over-voltage detection prevents the over-voltage in the high-side output characteristics.

This drive also features a programmable slew-rate setting. At a low slew rate, current surge is minimized and the noise is reduced. The high slew rate provides faster switching performance. Along with the integrated overtemperature protection, under-voltage lockouts are also included, making the drive truly safe. On top of that, this IC also has higher efficiency (up to 96%), further reducing the losses in the power converter.

Conclusion

The SI8286BC-ISR is a robust and reliable Isolators - Gate Driversfor two N-channel Power MOSFETs, IGBTs, or BJTs. Its wide power supply voltage range makes it suitable for various power converters. Furthermore, its integrated fault protection and adjustable slew-rate settings reduce the propagation delay and maximize system reliability and efficiency.
