CXDR75107内部计时器延迟输出返回到非活动状态,以确保系统正确复位。延迟时间td在VCC上升到阈值电压VIT+以上后开始。当电源电压降到阈值电压VIT-(2)以下时,输出再次激活。不需要外部组件。所有器件都有一个由内部分压器设置的固定感应阈值电压VIT。CXDR75107包含一个手动复位输入MR。MR处的低电平导致RESET(RESET)激活。产品频谱设计用于2.5V、3V、3.3V和5V的电源电压。这些电路以SOT-23-5封装提供。CXDR75107主要为基于DSP和处理器的系统提供电路初始化和时序监控。在通电期间,当电源电压VCC高于1.1 V时,将断言复位(重置)。此后,电源电压监管器监控VCC,并在VCC保持在阈值电压以下时保持复位(重置)激活

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
