德州仪器的低静态电流可编程延迟监控电路TPS3808G09dbvr Low Quiescent Current, Programmable-Delay Supervisory Circuit 集成电路TPS3808G09dbvr的说明 The TPS3808xxx family of microprocessor supervisory circuits monitor system voltages from 0.4V to 5.0V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and manual reset (MR) return above the respective thresholds. The TPS3808 uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3V. The reset delay time can be set to 20ms by disconnecting the CT pin, 300ms by connecting the CT pin to VDD using a resistor, or can be user-adjusted between 1.25ms and 10s by connecting the CT pin to an external capacitor. The TPS3808 has a very low typical quiescent current of 2. 集成电路TPS3808G09dbvr的特性 Power-On Reset Generator with Adjustable Delay Time: 1.25ms to 10s Very Low Quiescent Current: 2.4μA typ High Threshold Accuracy: 0.5% typ Fixed Threshold Voltages for Standard Voltage Rails from 0.9V to 5V and Adjustable Voltage Down to 0.4V Are Available Manual Reset (MR) Input Open-Drain RESET Output Temperature Range: –40°C to +125°C Small SOT23 and 2mm × 2mm QFN Packages APPLICATIONS -集成电路TPS3808G09dbvr的应用 DSP or Microco*oller Applications DSP或单片机应用 Notebook/Desktop Computers 笔记本和台式电脑 PDAs/Hand-Held Products pda /手持产品 Portable/Battery-Powered Products 便携式/电池驱动的产品 FPGA/ASIC Applications 现场可编程应用 深圳市鹏展翅电子有限公司(pzcdz),主营TI/BB/NS/ADI品牌全新原装IC，公司团队专注于TI品牌*集成电路10多年,现货多多，TI/BB系列很多型号具有*势，可全线订货。
