Shrinking electronic circuits place demands on power supplies to keep pace. The latest PCMCIA-card formats force designers to consider converter topologies and keep a watchful eye for components that meet ultrathin-design requirements....

With the advent of broadband access, many companies have developed high voltage SLICs (subscriber line interface card) which control the ringing and voice transmission on phone systems. The SLICs essentially perform two functions. One is r...

摘要：本應(yīng)用筆記提供了一些利用Maxim API控制DS1WM 1-Wire總線主機的C語言例程。本文討論的內(nèi)容基于DS1WM已經(jīng)設(shè)計到FPGA或ASIC內(nèi)，主控CPU通過API調(diào)用控制DS1WM。DS1WM通過兩個文件(DS1WM.c和...

Abstract: Unwanted electromagnetic radiation referred to as EMI is emitted by all electronic systems, including switching regulators. Adopting spread-spectrum pulse-width modulation (SSPWM) as a control scheme enhances the suppression of E...

More and more aspects of our lives depend on the uninterrupted operation of electronic equipment and appliances. "Drive by wire" and "fly by wire" have become everyday realities. In automated plants especially, electronic equipment that fa...

摘要：當熱插拔控制電路的輸出發(fā)生短路時，會觸發(fā)內(nèi)部斷路器功能并斷開電路。但在內(nèi)部斷路器做出反應(yīng)之前，剛開始的短路電流可能達到數(shù)百安培。通常熱插拔控制器斷路器的...

Abstract: Output overvoltage protection is a critical feature for DC-DC converters in order to protect sensitive loads from permanent damage. The basic requirements for an overvoltage protection (OVP) circuit are precise sensing of the out...

Abstract: When it is necessary to plug in a board into a system that is currently powered, it is critical to control the inrush current to prevent damage/system fault conditions. This application provides a simple circuit to achieve this f...

摘要：歐盟最近頒布的限制有害物質(zhì)指令(RoHS)禁止在電子電氣元件中使用金屬鉛(Pb)。受該指令影響，裝配流程也必須是無鉛的(無Pb)。盡管DS2502倒裝芯片在RoHS指令擁有豁免權(quán)，但其...

摘要：在筆記本電腦和便攜DVD應(yīng)用中，音頻系統(tǒng)存在一個問題，即揚聲器的動態(tài)范圍有限，無法滿足實際應(yīng)用的要求。由于受產(chǎn)品尺寸的制約，揚聲器的尺寸非常小，只能在有限的...

摘要：本文討論了汽車應(yīng)用中的典型供電架構(gòu)，并探討了如何在基本的電源設(shè)計中增加有源電壓限制功能，闡明了集成限壓器的必要性。文中還提供了幾個Maxim的有源電壓限幅器設(shè)計...

Abstract: This application note describes the hardware and software differences between the Dallas Semiconductor DS21Q42 and the DS21Q41B quad port framer devices. The DS21Q42 enhanced quad T1 framer offers a broader feature set while reta...

Abstract: Application Note 349 provides a detailed list of the features included in the DS2152L that are not included in the DS2151Q T1 single chip transceiver (SCT). All of the original features of the DS2151Q have been retained. All soft...

Abstract: Tech Brief 7 provides the requirements for multiplexing four PCM streams into one 8MHz system backplane using the Dallas Semiconductor/Maxim DS2152 and DS2154 T1/E1 single chip tranceivers (SCTs). The DS2155, DS26528, DS26524, DS...

Abstract: The application note describes how to design a backplane of 8.192MHz that simultaneously connects to any four framers of the following: DS21Q41 quad T1 framer, DS21Q43 E1 framer, DS2141 T1 controller, DS2151 T1 single chip transc...

Abstract: Application note 303 provides information on connecting the DS2151 and DS2153 single chip transceivers (SCTs) to a 16-bit DSP: the Analog Devices ADSP2181. Interconnections between the DS2151 or DS2153 parallel ...

Abstract: This application note describes how the DS2141A, DS2143, DS2151, and DS2153 interface to the SGS-Thomson M3488. Also shown are waveforms and timing diagrams of the different pins that are used for interfacing with M3488. ...
