描述

The 1SP0351 single-channel plug-and-play gate driver is based on the SCALE-2 chip set. It is optimized for operation of 4500 V Press-Pack IGBT power modules from manufacturers such as Toshiba, Westcode and ABB.

The gate driver features optical interfaces and a built-in DC/DC power supply with basic isolation. Enhanced level of protection is provided by implemented short-circuit monitoring.

Power Integrations¡¯ Dynamic Advanced Active Clamping allows an extended DC-link voltage range in IGBT off-state for up to 60 s.

The SCALE-2 ASIC chipset uses sophisticated digital control techniques to reduce component count by as much as 85% compared with conventional solutions, significantly increasing reliability.
