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

该问题由某客户提出，发生在 STM32F207VET6 器件上。据其工程师讲述：部分芯片无法通过拉低NRST PIN产生复位。该现象一旦上电复位后无法重现。客户的应用中通过外部硬件看门狗定时给NRST PIN送低电平产生复位。正常情况下，MCU会给外部硬件看门狗喂狗。

使用说明本程序完全参照龚建伟《串口调试助手V2.2》制作而成，原软件是用VC编写的，我将它改用Delphi编写，作为我学习串口编程的一个例子与工具使用。其中用到串口控件为ComPort，该控件为开源软件，各大网站均有下载，目前最新版为3.0。使用平台： WIN9X/NT/2000/XP 本软件目前仅供三线制（NONMODEM）串口调试之用，所有功能均置于界面上，一目了然，其义自明，这里仅对十六进制发送作一说明：十六进制发送：选中（CHECK）十六进制发送后，程序会自动从发送框取16进制数发送，最好按16进制格式填写，例如：12 34 56 77 10使用窗口悬浮功能：点击程序左下角的针状按钮可以使程序置于最上层，保持可见；放大至全屏：当需要扩大接收窗口以方便观看数据时，可以点击右上角最大化按钮另外：还要注意的是调试串口时，插拨串口接头应尽量关闭计算机，至少保证一端是关闭的。＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝这个程序是我在网上下载的，在使用中发现有些问题：1、编译后发现在自动发送时有假死机现像，已经修正;2、把按键改在右边了，方便操作。
