电源技术 电信、数据通信和工业电源产品
In industrial applications, high voltage power supply spikes with durations ranging from a few microseconds to hundreds of millisecondsare commonly encountered. The electronics in these systems must not only survive transient voltage spikes, but in many cases alsooperate reliably throughout the ev ...
电源技术 具有宽输入范围的微型单片降压型稳压器
 
Automotive batteries, industrial power supplies, distributedsupplies and wall transformers are all sources ofwide-ranging high voltage inputs. The easiest way to stepdown these sources is with a high voltage monolithicstep-down regulator that can directly accept a wide inputrange and prod ...
电源技术 利用高压看门狗定时器加强汽车安全系统
 
Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...
单片机编程 基于AVR的新型防汽车追尾安全装置设计
针对目前汽车追尾事件频发问题，提出一种防汽车车前和车后追尾的安全装置设计。该设计以高性能、低功耗的8位AVR微处理器ATmega8L为核心，结合霍尔式车速传感器、激光雷达测距装置和MMA7260QT加速度传感器，能够兼顾车前和车后，摒弃以往设计中只考虑车前或车后单一性缺点，尤其适用于高速、夜晚或新手行车。
