For silicon-, GaN- or SiC-based systems:
The "turbocharged" ISO gate driver for high-speed switches

Si823-Rennwagen_720px.jpg 

Ideal for controlling Power MOSFETs and IGBTs in switch-mode power supplies, inverters and motor control systems.

The ISO drivers of the Si823Hx series from SILICON LABS provide symmetrical 4 A control with a robust driver output of 30 V.

The "turbo lag" is extremely small here - the propagation delay is only 30 ns (max.)

The drivers support a dielectric strength of 5000 V at the output pins. Overvoltage protection and a high resistance to electromagnetic interference are also guaranteed.

The high CMTI of 125 kV/µs is a distinctive feature of the Si823Hx series.
CMTI stands for 'Common Mode Transient Immunity'. This describes the capacity of an isolator to maintain safe and normal operation when it is subjected to a high common mode transient on one
(or both) sides of the isolator. The CMTI is specified as the maximum voltage slew rate.

Technical data of the Si823Hx series:

  • Single or dual isolated drivers in one housing
  • 2.5 kVrms and 3.75 kVrms isolation options
  • DIS or EN pin for asynchronous shutdown option
  • VDDI of 3.0 V - 5.5 V
  • PWM and dual driver versions
  • 4.0 A sink/source peak output
  • 30 ns max propagation delay
  • Transient immunity: >125 kV/μs
  • Deglitch and noise filter options for robust operation in noisy environments
  • Robust 30 V supply
  • Overtemperature protection
  • AEC Q100 qualification
