BD47XXG seriesHigh-accuracyLow current consumption BD47XXG is a series of RESET ICs developed to prevent system error at transient state when the power of CPU and logic circuit switches ON/OFF or shutdown. These ICs consist of Power, GND, and reset output to detect power supply voltage of various systems and to output reset signal. These ICs are more practical for portable products because of their ultra-small package and low current consumption.Description1) Detection voltage: 0.1V step line up 1.9~4.6V(Typ.)2) High-accuracy voltage detection Vs ±2%(Max.)3) Low current consumption4) "L" reset output of open collector 5) Small SMP5 package FeaturesPortable products, Equipments with CPU and logic circuit ApplicationsSeries characteristicsGeneral-purposeRESET ICAbsolute Maximum Ratings(Ta=25˚C)Application Circuit*2 TPHL : Vcc=(Vs typ.+0.4V)Æ(Vs typ.–0.4V)Electrical characteristics Timing waveform Transfer delay time measurement circuitVCCVOUTVS0V VS+VCCNote) The ratings shown above indicate breakdown limit of the pin and should not be regarded as the values that guarantee the operation.* Derating : 1.5mW/˚C for operation above Ta=25˚CCharacteristic diagram and Measurement circuit (When BD4729G is measured.)I c c (µA )Vcc (V)Current consumptionOperating limit voltage'L' output currentI/O characteristicNCV o u t (V )Vcc (V)V o u t (m V )Vcc (V)V o u t (m V )Iol (mA)Setting of the RESET signal delay timeDelay time can be set by capacitor C L and resistance R L connected to the output pin as shown below.CL is charged by R L when Vcc is rising. The delay time caused by charging is determined by thetime constant of C L, R L and the threshold voltage of RESET pin. RESET IC discharges C L forcedly when Vcc is falling.

astma473标准中文版

astma473标准中文版
ASTMA473标准（ASTM A473 standard）是由美国材料与试
验协会（American Society for Testing and Materials，ASTM）
制定的钢材标准，适用于钢材的化学成分、力学性能和热处理要求的规定。

ASTMA473标准覆盖了一系列不同类型的钢材，包括不锈钢、合金钢和碳钢等。

该标准规定了钢材的化学成分要求，包括元素的最大和最小含量，以及钢材的制造方法和加工要求。

此外，ASTMA473还规定了钢材的力学性能要求，包括抗拉
强度、屈服强度、延伸率和冲击韧性等指标。

这些性能要求对于确保钢材在使用过程中的可靠性和安全性非常重要。

此外，ASTMA473标准还涉及到钢材的热处理要求，包括固
溶处理、时效处理和淬火等工艺的规定。

这些热处理工艺可以改变钢材的组织和性能，使其具有特定的力学性能和耐蚀性能。

ASTMA473标准的应用范围广泛，适用于各个行业的钢材制
造和使用。

它为钢材的生产商、供应商和使用者提供了一种统一的标准，以确保钢材的质量和性能符合要求，从而保证使用者的安全和利益。

1n4734a稳压二极管参数

1n4734a稳压二极管参数
1N4734A是一种稳压二极管，它的参数包括额定工作电压、最
大反向工作电压、最大稳定电流和功耗等。

具体参数如下：
1. 额定工作电压，1N4734A稳压二极管的额定工作电压为5.6V。

这意味着在正向工作时，它会将电压稳定在5.6V附近。

2. 最大反向工作电压，1N4734A稳压二极管的最大反向工作电
压为 5.6V。

这意味着当电压超过 5.6V时，稳压二极管会开始导通，将电压稳定在5.6V。

3. 最大稳定电流，1N4734A稳压二极管的最大稳定电流为37mA。

这意味着在正常工作条件下，它可以稳定地通过37mA的电流。

4. 功耗，稳压二极管的功耗取决于工作电压和稳定电流。

在额
定工作电压下，稳压二极管的功耗可以通过额定工作电压和最大稳
定电流来计算。

总的来说，1N4734A稳压二极管的参数决定了它在电路中的稳
压特性和工作条件。

在设计电路时，需要根据这些参数来选择合适的稳压二极管，以确保电路的稳定工作。
