UG475: Si823Hx Gate Driver Board The Si823Hx Gate Driver Board (GDB) is ideal for driving power modules and discrete transistors. This two-channel isolated gate driver solution features a TECHNICAL FEATURES differential digital interface, optimized on-board isolated power supply, and user-configurable turn-on and turn-off gate resistors. Status indicator LEDs and Two input, high-side/low-side gate driver test points make evaluation and prototyping easy. User programmable dead-time Overlap protection Ordering Information: 4 A symmetric peak output current Si823H-AAWA-KIT - 1 gate resistors Available with 1 or 4 gate resistors Independent control of turn on/turn off timing through Si823H-ABWA-KIT - 4 gate resistors gate resistor selection Flexible isolated power supplies Additional System Components: 5 kV safety rated isolation RMS The Si823Hx GDB is highly versatile but must be combined with other compo- 125 kV/s common mode transient immunity (CMTI) nents to form a complete system. You can choose various vendors elements DC bus voltage up to 800 V to complete your evaluation or prototyping system and tailor it to your specific Reverse polarity protection for 12 V input supply needs.
