Product Description

●Si8234 Isolated Gate Driver

●The Si8220/1 are "opto-input", package and pin compatible single-channel isolated gate driver upgrades to HCPL-3120 and other optically-coupled gate drivers. These devices can connect to optocoupler external input circuits (e.g. voltage source and series limiting resistor) and offer significant improvements in performance and reliability.

●Features:

● Integrated isolator plus dual gate drivers in one package

● Up to 5 kVrms input-to-output differential voltage isolation

● Withstands 1500 VDC peak driver-to-driver isolation

● HS/LS and dual versions

● Up to 8 MHz switching frequency

● 0.5 A peak output (Si8230/1/2)

● 4.0 A peak output (Si8233/4/5)

● Independent HS and LS 2 wire inputs or single wire PWM input versions

● Opto input mode (Si822x) with single channel 0.5 A or 2.5 A drivers

● Common-mode transient immunity >25 kV/μs

● Overlap protection and programmable dead time (Si8230/1/3/4)
