UCC21736-Q1 是一款電隔離單通道柵極驅動器，用于具有高達 2121V 直流工作電壓的 SiC MOSFET 和 IGBT，具有高級保護功能 功能、出色的動態性能和穩健性。UCC21736-Q1 具有高達 ±10A 的峰值拉電流和灌電流。
輸入側通過 SiO2 電容隔離技術與輸出側相隔離，支持高達 1.5kVRMS 的工作電壓、12.8kVPK 的浪涌抗擾度，隔離層壽命超過 40 年，并提供較低的器件間偏移、大于 150V/ns 的共模噪聲抗擾度 (CMTI)。
UCC21736-Q1 具有高級保護功能 功能，如快速過流和短路檢測、分流電流檢測支持、故障報告、有源米勒鉗位、輸入和輸出側電源 UVLO（用于優化 SiC 和 IGBT 開關行為）和穩健性。可以利用 ASC 功能在系統故障事件期間強制打開電源開關，從而進一步提高驅動器的多功能性并消減系統設計工作量、尺寸和成本。
