Low power STANDBY requirements are typically associatedwith battery-powered systems. Automotive systems,for example, commonly require power supplies tomaintain output voltage regulation even under no-loadconditions—while drawing minimal quiescent current topreserve battery life. Rising energy costs, however, haveextended the need for low current STANDBY operation toline-powered systems, such as small plugged-in appliancesfor home and business.

Battery powered applications that have a signifi cantamount of time in STANDBY mode, require electrical circuitsto operate with a low quiescent current to preserve batterylife. The LTC3835 synchronous step-down controlleris an excellent solution with its ultralow quiescent current(80μA). Other features make it uniquely qualifi ed tosatisfy the needs of automotive applications. A wide 4Vto 36V input voltage range protects the supply againsthigh input voltage transients and is compatible with lowvoltage cold crank conditions.

Industrial remote monitoring systems and keep-alivecircuits spend most of their time in STANDBY mode. Manyof these systems also depend on battery power, so powersupply effi ciency in STANDBY state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converter is ideal for these systems, requiringonly 8.5μA of quiescent current in STANDBY mode. Thedevice integrates high value (12.4M/0.4M) output feedbackresistors, signifi cantly reducing input current whenthe output is in regulation with no load. Other featuresinclude an integrated 40V switch and Schottky diode,output disconnect with current limit, built in soft-start,overvoltage protection and a wide input range, all in atiny 8-pin 2mm × 2mm DFN package.

Handheld electronic devices play a key role in our everydaylives. Because dependability is paramount, handhelds arecarefully engineered with lightweight power sources forreliable use under normal conditions. But no amount ofcareful engineering can prevent the mistreatment theywill undergo at the hands of humans. For example, whathappens when a factory worker drops a bar code scanner,causing the battery to pop out? Such events areelectronically unpredictable, and important data storedin volatile memory would be lost without some form ofsafety net—namely a short-term power holdup systemthat stores suffi cient energy to supply STANDBY power untilthe battery can be replaced or the data can be stored inpermanent memory.

SPMC75低功耗操作:本應用例介紹如何設置使SPMC75F2413A進入節(jié)電模式。1.2 模式簡介SPMC75F2413A有標準模式和兩種節(jié)電模式(等待模式和就緒模式),相應功能如下: 標準模式(Normal)芯片在標準模式下運行耗電最大,所有的外設都可用。 等待模式(Wait)等待模式下,只有CPU掉電停止工作以降低功耗。其它外設保持著先前的狀態(tài)并且功能可用。一旦喚醒,CPU將繼續(xù)工作,執(zhí)行接下去的指令。 就緒模式(STANDBY)就緒模式下所有的模塊都變?yōu)闊o效,此時功耗達到最小。喚醒后,CPU復位并回到標準運行模式。其它外設可以通過軟件分別設置關(guān)閉。就緒模式下所有功能都會關(guān)閉,只有系統(tǒng)時鐘仍在工作。如果按鍵喚醒功能為有效,這兩種模式都可以通過按鍵喚醒。具體喚醒源的分類及喚醒功能的介紹請參考《SPMC75F2413A編程指南》。【注意】如果MCP定時器3或定時器4已經(jīng)處于PWM輸出模式時,芯片不會進入等待或就緒模式。同樣在仿真模式下也無法進入等待或就緒模式。

The LTC®3207/LTC3207-1 is a 600mA LED/Camera driverwhich illuminates 12 Universal LEDs (ULEDs) and onecamera fl ash LED. The ULEDs are considered universalbecause they may be individually turned on or off, setin general purpose output (GPO) mode, set to blink at aselected on-time and period, or gradate on and off at aselected gradation rate. This device also has an externalenable (ENU) pin that may be used to blink, gradate, orturn on/off the LEDs without using the I2C bus. This may beuseful if the microprocessor is in sleep or STANDBY mode. Ifused properly, these features may save valuable memoryspace, programming time, and reduce the I2C traffi c.

The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its
customers with both voice and comprehensive data services. With an i-mode phone, users can
exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible
Internet sites.
The i-mode phone contains a browser that displays i-mode compatible HTML web pages.
Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode
browser. You can also use the phones’ My Picture and STANDBY Screen applications to view Flash
Lite movies. Although a number of manufacturers produce 505i phones, all of them support the
same Flash Lite functionality.
