800mA Linear Li-Ion Battery Charger

describe

TP4060 is a complete single-cell lithium-ion battery charger with reverse polarity protection for positive and negative polarity of the battery. It has a larger charging current of 800mA and a more stable current consistency. Its constant current/constant voltage linear control, SOP package and low external component count make the TP4060 ideal for portable applications. TP4060 can work with USB power and adapter power.

External sense resistors and blocking diodes are not required due to the use of an internal PMOSFET architecture, coupled with a reverse charge protection circuit. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions. The full voltage is fixed at 4.2V, while the charge current can be set externally with a resistor. When the battery reaches 4.2V, the charging current drops to 1/10 of the set value, and the TP4060 will automatically terminate the charging.

When the input voltage (AC adapter or USB power supply) is removed, the TP4060 automatically enters a low current state and the battery leakage current is below 2uA. Other features of the TP4060 include a charge current monitor, undervoltage lockout, automatic recharge, and two status pins to indicate end of charge and input voltage engagement.

This is Ren Yuxin's first group interview since Tencent's third major organizational restructuring on September 30 last year, and it is also his rare face-to-face interview with the media in the past five years. He laughed and said that he was receiving a "group interview". This is also like a one-year platform and content business group (PCG) at the helm, and even an "interview" for Tencent.

Ren Yuxin, Chief Operating Officer of Tencent and President of the Platform and Content Business Group (PCG).

Core tips:

1. Ren Yuxin said frankly that the two business groups of MIG and OMG were passively taken over before, and the person in charge of the original business group resigned or adjusted his position, but this time he took over PCG relatively actively. More, we participated in the design together.” At present, 80% of his energy is on the management of PCG, and he said that investment in PCG is long-term, and short-term returns are not the focus.

2. In the face of Tencent's late development in the short video business, and related rumors of Tencent's investment in Kuaishou and Weishi. Ren Yuxin set the tone and said, "We must enter the short video field, and Weishi products must be made, and they must be placed within the company and do our best to do it well."

3. In terms of organizational management, Ren Yuxin devotes energy to unifying the methodology of employees from different business groups, so that employees with OMG content genes, MIG tool thinking and SNG social advantages use a consistent language, tools and platforms to communicate.

4. In terms of business logic, Ren Yuxin emphasizes jumping out of closed-loop thinking and creating a content center and a technology center.

5. In terms of team governance, Ren Yuxin and the eight vice presidents (VPs) of PCG established a senior partner system to be responsible for the success or failure of the business group in a collective form.

6. In terms of product thinking, Ren Yuxin emphasizes user-driven rather than industry competition-driven.

Beijing News (Reporter Baibai Lei Cheng Zijiao) On September 19, Tencent Chief Operating Officer and President of the Platform and Content Business Group (PCG) Ren Yuxin appeared at the Binhai Building, Tencent's new headquarters, dressed in black and red sneakers. 25th floor meeting room.

This is Ren Yuxin's first group interview since Tencent's third major organizational restructuring on September 30 last year, and it is also his rare face-to-face interview with the media in the past five years. He laughed and said that he was receiving a "group interview". This is also like a one-year platform and content business group (PCG) at the helm, and even an "interview" for Tencent.

During the strategic upgrade and structural adjustment a year ago, the original Mobile Internet Business Group (MIG), Online Media Business Group (OMG), and Social Network Business Group (SNG) were broken up into PCG, and the Interactive Entertainment Business Group ( IEG)'s animation, film and other business lines are also included.

This business group, which almost has Tencent's strongest content platform and resources, is described by the outside world as a collection of "Netflix + Disney +...", and its volume exceeds that of most domestic companies. But the challenge left to Ren Yuxin is equally huge: how to make more than 10,000 people with different genes such as content, social networking, and tools to work together? How to play the role of content and platform "1+1 is greater than 2", and enhance the commercial value of IP? How to make up for the relative shortcomings of information flow and short videos while consolidating the foundation of Tencent's long content?

As unprecedented as the emergence of this huge business group, what Ren Yuxin has to do also has no frame of reference.

In terms of organizational management, he devoted his energy to unifying the methodology of employees from different business groups, so that employees with OMG content genes, MIG tool thinking and SNG social advantages communicate using a consistent language, tools and platforms; in terms of business logic, he emphasized jumping out of the closed loop Thinking, creating a content middle platform and a technology middle platform; in terms of team governance, he established a senior partner system with the eight vice presidents (VPs) of PCG, and is responsible for the success or failure of the business group in a collective form; in product thinking, he Emphasize user-driven rather than industry competition-driven.

From QQ and WeChat to Yingbao and browsers, is Tencent only good at making traffic-based products and not good at making short videos and live broadcasts? Ren Yuxin holds an objection to this. In his opinion, ecological products do not rely on human sea tactics to connect with external content creators, but to build a self-help and efficient platform that allows both internal and external work to be carried out conveniently and reduce Communication costs and improve ecological efficiency.

In the past year, PCG spent a lot of energy on the construction of the content platform and the technology platform, hoping to deposit high-quality content, and at the same time integrate content-related tools and processes into this platform. Zeng Yu, the VP (Vice President) responsible for the technical middle and backstage, has recently become the new head of the content middle platform "Penguin", which also marks the new goal of Penguin to improve platform efficiency with technology.

In the face of Tencent's late development in the short video business, and related rumors of Tencent's investment in Kuaishou and Weishi. Ren Yuxin set the tone and said, "We must enter the short video field, and Weishi products still need to be built, and we must put them in the company and do our best to do it well", but he emphasized that "We do not regard Weishi as determining the success or failure of the short video field. , an important strategy (product) for PCG's success or failure". At the same time, in addition to the built-in short video content in Tencent Video and Tencent News, and the independent short video application Weishi, PCG is also researching new short video products, which may be a subdivision of the intersection of social and content.

Ren Yuxin believes that in the past year, PCG's advantages in long-term content such as film and television, reading, animation, and games have been further consolidated, and a large number of high-quality IP have been accumulated. "Tencent has a huge amount of IP reserves in history, and it is impossible for any company to complete such reserves in a short period of time," Ren Yuxin said. The report shows that the total value of IP or IP-derived this year has reached 200 billion yuan. There are 274 original IPs in China, and Tencent owns 110, covering games, literature, animation, film and television and other fields.

Ren Yuxin is Tencent's stock market leader. In 2001, he joined Tencent from Huawei to be in charge of community technology, at a time when the Internet giant was still plagued by profitability problems. In 2004, Tencent encountered a bottleneck due to the agency of the Korean game "Triumph". Ren Yuxin started from chess and card games and spent five years making Tencent the world's largest game company, and also derived literature, animation, film industry, e-sports and other related businesses; In 2013, Liu Chengmin left Tencent and handed over to Ren Yuxin the MIG business group, which has always been called the "Millennium Second" in the fields of security, app stores, browsers and other fields. .

In an interview on the 19th, Ren Yuxin admitted that the previous takeover of the two business groups of MIG and OMG was passive, and the person in charge of the original business group resigned or adjusted his position, but this time he took over PCG relatively actively, "compared to those two times. , I will participate more and participate in the design together." At present, 80% of his energy is on the management of PCG, and he said that the investment in PCG is long-term, and short-term returns are not the focus. In an interview with the Beijing News and other media, he also talked about his thoughts on Tencent's innovation capabilities, the rejuvenation of the cadre team, and the internal horse racing culture.
