The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2µA. The PW4055 can be put into shutdown mode, reducing the supply current to 25µA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product label (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below. Test Lead Ratings Test Leads - 1000V, 15A Fine Tip Probe Attachments - 300V, 3A Mini Grabber Attachment - 300V, 3A SMT Grabber Attachments - 300V, 3A Operation The Fine Tip, Mini Grabber, and SMT Grabber attachments plug onto the probe end of the Test Leads. Maintenance If any portion of the Test Lead Set is worn or damaged, do not use. Replace with a new Agilent 3413

最近经理通知要做项目了，让我选型一个LCD开始试着做下。这是我用仿真实现的一个smt32的硬件SPI1来驱动的ST7735R，难度挺小的，因为大部分的代码LCD的厂商已经给我们提供了，我们主要修改成硬件SPI来驱动就好了。 此次仿真上面有2个问题，不知道是代码的问题还是仿真图上的问题。第一个问题是仿真运行时有时会出通信数据传输问题，导致指令越界报警，这个可能是SPI不稳定导致的；第二个问题是在改用SPI2或者SPI3来驱动没有任何反应，猜测是代码时钟没开对或者仿真图上面还要加上具体晶振。 代码工程和仿真工程都已压缩打包，可放心下载。。。先贴上仿真实现图： 再贴上部分代码：/**ST7735驱动**/#include "ST7735.h"#include "usart.h" u16 BACK_COLOR, POINT_COLOR; //背景色，画笔色 void WriteCommand_7735(u8 CmdData) //写指令{SPI_LCD_CS_LOW; //片选SPI_LCD_COMMAND_W;//写指令SPI_I2S_SendData(LCD_SPIx,CmdData);while (SPI_I2S_GetFlagStatus(LCD_SPIx, SPI_I2S_FLAG_TXE) == RESET){}SPI_LCD_CS_HIGH;} void WriteDate_7735(u8 Data) //写8位数据{SPI_LCD_CS_LOW; //片选SPI_LCD_DATA_W;//写数据SPI_I2S_SendData(LCD_SPIx,Data);while(SPI_I2S_GetFlagStatus(LCD_SPIx, SPI_I2S_FLAG_TXE) == RESET){} SPI_LCD_CS_HIGH; } void WriteDate16(int data) //写16位数据{WriteDate_7735(data>>8);WriteDate_7735(data);} 字符限制了，贴不了多少，2积分即可下载。。。
