电源技术 如何保护集成FET的电源开关
Abstract: Some types of loads require more current during startup than when running. Other loads can be limited to a lower-powercurrent during startup but require a higher operating current. This article describes an application circuit that automatically adjusts apower circuit’s overcurrent ...
电源技术 电池管理系统的多点温度测量方案
 
Abstract: It is critically important that lithium-ion battery stacks have a good battery-management system for monitoring many cellvoltages and cell temperatures. Without that monitoring, thermal runaway can lead to a battery explosion. This design idea presentsa low-power circuit that me ...
