Two TP4101 circuits:

Circuit Diagram Features Remarks

1. Programmable charging current 3-600mA;

With lithium battery charging + lithium battery protection function, a total of 7 devices

2. 5V power supply reverse connection protection;

3. Battery reverse connection protection;

4. With battery over-discharge (2.6V), over-charge (maximum

TP4101

circuit 4.3V), overcurrent protection (maximum 1.7A);

5. The leakage current of the BAT pin is less than 4uA;

6. Thin package TSOT23-5 (maximum thickness

0.9mm);

7.20% constant current precharge, C/10 charge termination,

The charging voltage accuracy is as high as 4.2±1%;

8. Wide input voltage 4-8VDC, single light indication;

advantage:

Both TP4100 and TP4101 have the function of lithium battery charging + lithium battery protection, which can fully realize the traditional single lithium battery charging + lithium battery protection (DW01+8205A scheme) circuit.

There are few peripheral devices in the circuit, which can reduce the cost of procurement, production and design; the application of small-sized products can save valuable effective space;

Power adaptive function, when the power supply Vcc is insufficient, the voltage drops. When it is as low as 4.4V, the adaptive circuit starts and automatically reduces the charging current until Vcc no longer decreases. This function can use high current charging for USB or low-power power adapters, The solar cell is used as the power source, and the power reset or restart is avoided.

3. Traditional charging + lithium battery protection circuit:

TP4057

Main function remarks of charging circuit circuit diagram

It can realize battery charging function + dual light indication.

A total of 7 devices without lithium battery protection function

DW01 Lithium

Electrical protection circuit

It can realize lithium battery protection function (overcharge, overdischarge, overcurrent). Does not have lithium battery charging

Electric function, need to add 2 more

NMOS, 6 devices in total

shortcoming:

Compared with TP4100/TP4101, the traditional charging + lithium battery protection circuit: there are more peripheral devices in the circuit, the cost will be higher, it will take up 1-2 times more effective space to put it, and the two circuits need to be added together at least 7+6= 13 devices;

It does not have input reverse connection protection, battery reverse connection protection, and mistakes in the production process will burn the circuit;

This year is destined to be an extraordinary year. Since 1987, the annual WWDC, which has never fallen, is also the first time in history that offline activities have been cancelled and changed to online live broadcast mode. However, the online live broadcast does not affect people's attention to Apple's "wind vane" WWDC. According to the practice of previous years, Apple's full-platform operating systems will be updated at WWDC, including iOS, MacOS, iPad OS, and more. At the same time, new hardware products such as the Mac Pro and Pro Display XDR introduced last year are also likely.

On the eve of this year's WWDC, it was revealed that Apple will replace the Intel processors on the current Mac computers with its own ARM-based processors, which has become one of the most anticipated hot spots of WWDC 2020. Today, there are still 3 days before the opening of WWDC 2020. Huaqiang Electronic Network has collected and sorted out the relevant news disclosed by major media and industry insiders so far, so that everyone can review the knowledge points before participating in WWDC 2020.

In fact, there were rumors about this news as early as 2018. At that time, a Reddit netizen posted an analysis article, guessing that the first ARM Mac device is expected to be seen within three years, and the desktop and mobile application ecosystems will be opened up. Looking back at this news in 2018, probably not many people would believe it. After all, the country that x86 has made for so many years is not so easy to be broken by ARM.

However, looking at the history of Mac computers, in fact, Apple's use of Intel processors with x86 architecture was only officially announced at WWDC in 2005, just 15 years ago. As early as 1988, Jobs claimed that all computer architectures and all computer systems have a 10-year lifespan, and then Apple has indeed experienced the journey from Motorola to PowerPC to Intel.

Bloomberg also said in a recent report that Apple will release its first ARM-based Mac at WWDC 2020 as soon as possible, using the A14 chip. However, changing system platforms can be a nightmare for developers. Referring to the time schedule of Apple's announcement of switching to the Intel platform in 2005, this year's WWDC is more likely to only announce relevant news and not release hardware, leaving enough time for developers to adapt.

After the smooth iteration of the previous two years, iOS may be different this year. Screen widgets that existed in various concept UI videos years ago may really be here this time.

Some foreign media found from the code of the early leaked version of iOS 14 that iOS 14 will add a "new list view" on the basis of retaining the grid layout of the application. Users can view all the applications on the device in the scrolling list of the page, roughly The effect is similar to the Apple Watch's list view. At the same time, there is also news that iOS14 will add elements of desktop widgets, similar to Android, and widgets can be placed anywhere on the home page at will. Developers can create three different types of icon styles to choose from: classic static icons, dynamic icons that display data and buttons, and full-sized widgets.
