目录产品概述 返回TOP An internal timer delays the return of the output to the inactive state to ensure proper system reset. The delay time, td, starts after VCC has risen above the threshold voltage VIT+. When the supply voltage drops below the threshold voltage VIT- (2), the outputs becomes active again. No external components are required. All the devices have a fixed-sense threshold voltage VIT- set by an internal voltage divider. The CXDR75107 incorporate a manual reset input MR . A low level at MR causes RESET (RESET) to become active. The product spectrum is designed for supply voltages of 2.5V, 3V, 3.3V, and 5V. The circuits are available in a SOT-23-5 package The CXDR75107 provide circuits initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET (RESET) is asserted when supply voltage VCC becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VCC and keeps RESET (RESET) active as long as VCC remains below the threshold voltage产品特点 返回TOP „ Power-On Reset Generator With Fixed Delay Time of 200ms „ Manual Reset Input „ Push-Pull RESET and RESET Output „ Supply Voltage Supervision Range 2.5V, 3V, 3.3V, 5V „ Supply Current of 10μA at VCC=3.3V „ SOT-23-5 Package 应用范围 返回TOP „ Critical μP and μC Power Monitoring „ Industrial Equipment „ Programmable Controls „ Automotive Systems „ Portable/Battery-Powered Equipment „ Intelligent Instruments „ Wireless Communications Systems „ Notebook/Desktop Computers 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
