芯凯电子科技KTU1001，USB Type-C输出电压最高20V，为市场带来高水准过压保护解决方案

时间： 2023-12-27 来源：KineticTechnologies（芯凯电子公众号）

技术问答

芯凯电子科技KTU1001，这是一款具有过压保护功能的高速USB双路单刀双掷（SPDT）器件。凭借KTU1001，芯凯电子科技得以进一步扩展自己的USB端口保护产品系列，并为市场带来高水准的过压保护解决方案。

产品优势

KTU1001的推出迎合了市场需求，帮助设计者排除任何故障对USB端口的损害。USB Type-C输出电压最高为20V，一旦VBUS和邻近引脚发生短路，可能会造成故障且具有破坏性。KTU1001的工作电压范围为2.7V到5.5V，过压故障保护电压高达20V，额定浪涌电压则高达25V。

KTU1001耗电低至25µA，而且对过压条件的响应也超快，仅为100ns。在4.8V过压典型值下，反向阻断开关电阻、电容为 6Ω, 4pF，同时将带宽提高为大于1GHz -3dB。逻辑控制器件包括一个专用的引脚以及若干个独立的开/关引脚，该器件具有过压故障标志信号输出功能。KTU1001采用超小的封装，功耗低，使其成为USB端口保护的理想选择。

市场及应用

KTU1001可广泛应用于智能手机、平板电脑、移动设备、便携摄像机、数码相机、具有服务测试模式的电器设备、内置大容量存储设备，电信设备和机顶盒。

评价

Kinetic Technologies副总裁 David Nam：“USB Type-C在给用户带来许多好处的同时，也会导致诸多潜在故障风险，这是OEM设计人员需要加以防范的。保护USB端口下游的系统IC至关重要，而KTU1001则为市场带来最高水准的过压保护。相比市场同类产品，KTU1001卓越的节电效果，对移动设备来说意义重大。即使在故障条件下，超快速的故障过压保护也仍然能保持安全电压。”
