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 KIT CONTENTS life and dramatically higher reliability compared to opto-coupled gate drivers. The Si827x isolated gate drivers utilize Skyworks Solutions proprietary silicon isolation technology Si827x-based evaluation board (Si827x- supporting up to 2.5 kV withstand voltage per UL1577 and VDE0884. This technolo- EVB) RMS gy enables industry-leading common-mode transient immunity (CMTI), tight timing spec- Si8271, 1-input, 4 A, 2.5 kV Single RMS ifications, reduced variation with temperature and age, better part-to-part matching, and ISOdriver, and one of the following: extremely high reliability. It also offers unique features, such as separate pull-up/down Si8273, 2-input, 4 A, 2.5 kV High- RMS outputs, driver shutdown on UVLO fault, and precise dead time programmability. Driver Side/Low-Side ISOdriver outputs can be grounded to the same or separate grounds or connected to a positive or Si8274, PWM-input, 4 A, 2.5 kV RMS negative voltage. The TTL level compatible inputs with >400 mV hysteresis are available High-Side/Low-Side ISOdriver in individual control input (Si8271/2/3/5) or PWM input (Si8274) configurations. High Si8275, 2-input, 4 A, 2.5 kV Dual RMS integration, low propagation delay, small installed size, flexibility, and cost-effectiveness ISOdriver 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 Skyworks 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 designers end system.

Required Equipment The following equipment is required to demonstrate the evaluation board: 1 digital multimeter 1 oscilloscope (at least 2 channel) 1 dual dc power supply: 05 V and 015 V (or 2 single supplies) 1 function generator Assorted cables, leads and probes as necessary to connect equipment to EVB Si827x Evaluation Board (board under test) Si827x Evaluation Board User s Guide (this document) Note: Please note the voltage rating for the prepopulated components in the Si827x BOM section of this document before applying power to the ISOdriver and customer-specific output power stage. Applying a voltage to a component that is higher than its rating can cause permanent device damage. If the installed components do not meet the user s requirements, these components need to be replaced before proceeding. Skyworks Solutions, Inc.
