General Description The LM621 is a bipolar IC designed for commutation of brushless DC motors. The part is compatible with both three- and four-phase motors. It can directly drive the power switching devices used to drive the motor. The LM621 provides an adjustable dead-time circuit to eliminate ``shootthrough'' current spiking in the power switching circuitry. Operation is from a 5V supply, but output swings of up to 40V are accommodated. The part is packaged in an 18-pin, dual-in-line package.

FEATURES Unique 1-Wire interface requires only one port pin for communication Multidrop capability simplifies distributed temperature sensing applications Requires no external components Can be powered from data line. Power supply range is 3.0V to 5.5V Zero standby power required Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F ±0.5°C accuracy from -10°C to +85°C Thermometer resolution is programmable from 9 to 12 bits Converts 12-bit temperature to digital word in 750 ms (max.) User-definable, nonvolatile temperature alarm settings Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition) Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system

protel 99se 使用技巧以及常見問題解決方法:里面有一些protel 99se 特別技巧,還有我們經(jīng)常遇到的一些問題!如何使一條走線至兩個不同位置零件的距離相同? 您可先在Design/Rule/High Speed/Matched Net Lengths的規(guī)則中來新增規(guī)則設(shè)定,最后再用Tools/EqualizeNet Lengths 來等長化即可。 Q02、在SCHLIB中造一零件其PIN的屬性,如何決定是Passive, Input, I/O, Hi- Z,Power,…..?在HELP中能找到說明嗎?市面有關(guān) SIM?PLD?的書嗎?或貴公司有講義? 你可在零件庫自制零件時點選零件Pin腳,并在Electrical Type里,可以自行設(shè)定PIN的 屬性,您可參考臺科大的Protel sch 99se 里面有介紹關(guān)于SIM的內(nèi)容。 Q03、請問各位業(yè)界前輩,如何能順利讀取pcad8.6版的線路圖,煩請告知 Protel 99SE只能讀取P-CAD 2000的ASCII檔案格式,所以你必須先將P-CAD8.6版的格式轉(zhuǎn)為P-CAD 2000的檔案格式,才能讓Protel讀取。 Q04、請問我該如何標示線徑大小的那個平方呢 你可以將格點大小設(shè)小,還有將字形大小縮小,再放置數(shù)字的平方位置即可。 Q05、請問我一次如何更改所有組件的字型 您可以點選其中一個組件字型,再用Global的方法就可以達成你的要求。

Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler failure, or undervoltage condition occurs. A simple application is shown on how to implement thisfunction.

有時候,做元件封裝的時候,做得不是按中心設(shè)置為原點(不提倡這種做法),所以制成之后導出來的坐標圖和直接提供給貼片廠的要求相差比較大。比如,以元件的某一個pin 腳作為元件的原點,明顯就有問題,直接修改封裝的話,PCB又的重新調(diào)整。所以想到一個方法:把每個元件所有的管腳的X坐標和Y坐標分別求平均值,就為元件的中心。
