Si823H-ACWA-KIT | Si823Hx Gate Driver Board

Si823H2x two channel, 4A peak, isolated gate driver board with 0Ω gate resistors and +15V/-3.5V gate bias supplies.

The Si823Hx Gate Driver Board (GDB) is ideal for driving power modules and discrete transistors. This two-channel isolated gate driver solution features a differential digital interface, optimized on-board isolated power supply, and user-configurable turn-on and turn-off gate resistors. Status indicator LEDs and test points make evaluation and prototyping easy.

Features

• Two input, high-side/low-side gate driver with dead-time control and overlap protection
• 4 A symmetric peak output current
• Built-in +15 V and -3.5 V isolated power supplies
• 5 kV_RMS safety rated isolation
• 125 kV/µs common mode transient immunity (CMTI)
• DC bus voltage up to 800 V
• Reverse polarity protection for 12 V input supply
• Differential inputs for increased noise immunity
• Module temperature (NTC) output as frequency modulated digital signal
