TP4056

describe

The TP4056 is a complete single-cell Li-Ion battery using a constant current/constant voltage linear charger. Its SOP8/MSOP8 package with heat sink on the bottom and low external component count make the TP4056 ideal for portable applications. TP4056 can work with USB power and adapter power.

Due to the use of an internal PMOSFET architecture, coupled with an anti-reverse charging circuit, no external blocking diodes are required. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions. The charge voltage is fixed at 4.2V, while the charge current can be set externally with a resistor. The TP4056 will automatically terminate the charge cycle when the charge current drops to 1/10 of the set value after reaching the final float voltage.

When the input voltage (AC adapter or USB power) is removed, the TP4056 automatically enters a low current state, reducing battery leakage current to less than 2uA. The TP4056 can also be put into shutdown mode when power is available, reducing the supply current to 55uA. Other features of the TP4056 include battery temperature detection, undervoltage lockout, automatic recharge, and two LED status pins to indicate end of charge.

In the fight against the dodgy FCC, Huawei is ready to fight to the end.

Today, Huawei held a press conference at its Shenzhen headquarters, announcing that it officially filed an indictment in the U.S. court, requesting the court to find that the FCC’s decision to prohibit Huawei from participating in federally subsidized funds violated the U.S. Constitution and the Administrative Litigation Law. Song Liuping, Huawei's chief legal officer, said that Huawei submitted multiple rounds of factual basis and objections, but the FCC completely ignored these factual basis and opinions.

The cause of the incident originated from the recent November 22 (US local time), the FCC passed a decision to prohibit operators from using federal subsidy funds, the "Universal Service Fund (USF)" to purchase equipment from Huawei and ZTE. Moreover, the FCC even voted to recommend that all U.S. carriers involving Huawei and ZTE equipment remove and replace the two companies’ equipment from existing networks.

In this regard, Huawei issued a statement on November 23 saying that it firmly opposed the decision, because the FCC determined that Huawei constituted a national security threat without evidence, which not only violated the due process principle of the legislation, but also suspected illegal . Huawei said in a statement that banning carriers from buying Huawei equipment does not really improve the state of cybersecurity in the United States. Without the support of this funding, U.S. operators in many remote areas will not be able to continue to obtain competitive Huawei products and services, the competition in the U.S. telecom equipment market will be weakened, and ordinary consumers will have to pay more for network services. price.

Statement by Song Liuping, Chief Legal Officer of Huawei (Original)

Ladies and gentlemen, good morning, and welcome to today's press conference. This morning, Huawei filed an indictment asking the court to overturn an illegal decision passed by the Federal Communications Commission (FCC).

On Nov. 22, the FCC passed a decision to designate Huawei as a national security threat, a decision that would bar U.S. carriers from using the General Services Fund to buy Huawei equipment. Many users and small businesses in rural America still remain unconnected to mobile networks, a decision that will hurt them. The FCC claimed that Huawei posed a security threat, but FCC Chairman Ajit Pai offered no evidence, a practice the U.S. government has used recently.

"Huawei is a Chinese company." That was the only excuse he could give. He also tried to sow fear of Huawei, using terms such as "backdoor" to sow fear without providing any evidence, and other FCC commissioners have used the same rhetoric.

Now China Unicom has released the operating data for July 2019. Although their 4G users have risen slightly, they are still the least among the three major operators.

In July 2019, China Unicom had a net increase of 109,000 mobile billing users, reaching a total of 324.462 million. Among them, the net increase of 4G users was 3.793 million in the month, reaching a total of 242.732 million.

In terms of fixed-line business, China Unicom saw a net increase of 267,000 fixed-line broadband subscribers in the month, reaching a total of 83.68 million; and a net decrease of 28,000 local telephone users in the month, reaching a total of 54.291 million. It is reported that in June 2019, China Unicom added a net increase of 24,000 mobile billing users, a net increase of 3.031 million 4G users, and a net increase of 246,000 fixed-line broadband users.

Regarding the upcoming commercial 5G network, Wang Xiaochu said that China Unicom may not carry out 5G construction in all places in the future. At present, China Unicom is seeking cooperation with China Telecom and China Mobile. There are two possibilities and corresponding modes for follow-up cooperation:

1. Either cooperate with China Telecom, build and share, operate separately, and jointly improve the spectrum efficiency by taking advantage of the closeness of the two 5G frequencies, so as to jointly build 5G, maintain and operate separately, reduce maintenance costs, and facilitate settlement.

2. Either cooperate with China Mobile for roaming. In this way, China Unicom will give priority to key areas and areas with large traffic to cover 5G. In the rest of the region, China Mobile roams to allow Unicom users to use 5G services.
