General Description

The Si8220/21 is a high-performance, functional upgrade for optocoupled drivers, such as the HCPL-3120 and the HPCL-0302 providing 2.5 A of peak output current.

It utilizes Silicon Laboratories' proprietary silicon isolation technology, which provides a choice of 2.5, 3.75, or 5.0 kVRMS withstand voltages per UL1577.

This technology enables higher performance, reduced variation with temperature and age, tighter part-topart matching, and superior mon-mode rejection pared to optoisolated drivers.

Key Features

  • Functional upgrade for HCPL-0302, HCPL-3120, TLP350, and similar opto-drivers.
  • 50 ns propagation delay (independent of input drive current).
  • 14x tighter part-to-part matching versus opto-drivers.
  • 2.5, 3.75, and 5.0 kVRMS isolation.
  • Transient Immunity.
  • 30 kV/µs Under-voltage lockout protection with hysteresis Resistant to temperature and aging effects Gate driver supply voltage: 6.5 V to 24 V Operating temperature range:.
