SI8221
Overview
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.
- 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: -40 to +125 °C Cost-effective Narrow body SOIC-8 and Wide body SOIC-16 packages RoHS Compliant Pin Assignments: See page 19 Narrow Body SOIC NC 8 VDD 1 ANODE 2 7 VO CATHODE 6 VO 3 NC 4 5 VSS Top View Wide Body SOIC
