3 說明
UCC21750 是一款電隔離單通道柵極驅動器，設計用于直流工作電壓高達 2121V 的 SiC MOSFET 和 IGBT，具有先進的保護功能、出色的動態性能和穩健性。UCC21750 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，共模噪聲抗擾度 (CMTI) 大于 150V/ns。
UCC21750 包括先進的保護特性，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）。可以利用隔離式模擬至 PWM 傳感器更輕松地感測溫度或電壓，從而進一步提高驅動器的多功能性并簡化系統設計工作量、尺寸和成本。
