3 說明
UCC21756-Q1 是一款電隔離單通道柵極驅(qū)動器，設(shè)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(tài)性能和穩(wěn)健性。UCC21756-Q1 具有高達 ±10A 的峰值拉電流和灌電流。
輸入側(cè)通過 SiO2 電容隔離技術(shù)與輸出側(cè)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。
UCC21756-Q1 包括先進的保護特性，如快速過流和短路檢測、故障報告、有源米勒鉗位以及輸入和輸出側(cè)電源 UVLO（用于優(yōu)化 SiC 和 IGBT 開關(guān)行為和穩(wěn)健性）?？梢岳酶綦x式模擬至 PWM 傳感器更輕松地進行溫度或電壓檢測，從而進一步提高驅(qū)動器的多功能性并較少系統(tǒng)設(shè)計工作量、尺寸和成本。
