UG186: Si827x-EVB User's Guide
The Si827x isolated gate drivers are ideal for driving power switches used in a wide variety of power supply, inverter, and motor control applications, offering longer service life and dramatically higher reliability compared to opto-coupled gate drivers. The Si827x isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolation technology supporting up to 2.5 kVRMS withstand voltage per UL1577 and VDE0884. This technology enables industry-leading common-mode transient immunity (CMTI), tight timing specifications, reduced variation with temperature and age, better part-to-part matching, and extremely high reliability. It also offers unique features, such as separate pull-up/down outputs, driver shutdown on UVLO fault, and precise dead time programmability. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are available in individual control input (Si8271/2/3/5) or PWM input (Si8274) configurations. High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the family ideal for a wide range of isolated MOSFET/IGBT/SiC/GaN gate drive applications.
The Si827x evaluation board allows designers to evaluate Silicon Lab's Si827x family of high CMTI performance ISOdrivers. The boards come populated with the Si8271 and either the Si8273, Si8274, or Si8275 version of the family. The board includes screw terminals for quick evaluation of the devices’ key parameters and also includes test points on each devices’ pins to accommodate direct connection to the designer’s end system.
