3 说明

UCC21737-Q1 是一款电隔离单通道栅极驱动器，设计用于直流工作电压高达 2121V 的 SiC MOSFET 和 IGBT，具有先进的保护功能、出色的动态性能和稳健性。该器件具有高达 ±10A 的峰值拉电流和灌电流。

输入侧通过 SiO2 电容隔离技术与输出侧相隔离，支持高达 1.5kVRMS 的工作电压、12.8kVPK 的浪涌抗扰度，隔离层寿命超过 40 年，并提供较低的器件间偏移，共模噪声抗扰度 (CMTI) 大于 150V/ns。

UCC21737-Q1 包括先进的保护特性，如快速过流和短路检测、分流电流检测支持、故障报告、有源米勒钳位、输入和输出侧电源 UVLO（用于优化 SiC 和 IGBT 开关行为）和稳健性。可以利用 ASC 功能在系统故障事件期间强制打开电源开关，从而进一步提高驱动器的多功能性并消减系统设计工作量、尺寸和成本。
