style="height:30px" aria-hidden="true" class="wp-block-spacer"></div><p>NSI22C12是一款高性能高速隔离窗口比较器，基于纳芯微电容隔离技术，其输出与输入分离。该器件支持开漏输出以及锁存功能，并能提供极短的保护延时，以及高共模瞬态抗扰度，非常适合应用于系统中过流保护的场景。NSI22C12支持两种阈值调节模式，一种是20mV~ 320mV的外部电压输入可调，另一种是通过内置100μA电流源流经外部电阻器的?0mV至?20mV阈值可调。NSI22C12的故障安全功能包括VDD1缺失检测，简化了系统设计和诊断?/p><div date-time="1746018079" dir="atkaas" style="height:100px" aria-hidden="true"

class="wp-block-spacer"></div><p>工业电机驱动系统的应用环境比较复杂且恶劣，可能会出现桥臂直通、相间短路、接地短路等突发状况，导致过大的电流流入电机驱动器系统，从而使驱动器损坏。传统的过流检测设计采用通用比较器和隔离光耦的分立方案，响应时间在3~5µs 之间，随着功率器件从硅基的IGBT转向第三代半导体SiC和GaN，其短路耐受时间缩短?μs内，传统方案已经无法满足?/p><p>同时，通用运放/比较器共模电压耐受能力有限，在DC+过流和相电流过流检测等应用中较为局限，而如果只监控DC-过流，则无法覆盖到电机外壳对地短路的故障情况。纳芯微的隔离式比较器NSI22C12提供单芯片式隔离过流保护方案，能够覆盖更全面的故障场景，支持最?50ns的保护延时，双向过流保护，同时提供高?50kV/μs的CMTI (Common-Mode Transient Immunity，共模瞬态抗扰度)，大幅提升系统可靠性，支持客户的工业电机驱动系统采用更高功率密度的设计?/p><div date-time="1746018079" dir="pmlihq" style="height:30px" aria-hidden="true" class="wp-block-spacer"></div><figure
