TP5410

TP5410

(1A lithium battery charging and 5V/1A boost control chip)

describe

TP5410 is a single-cell lithium-ion battery charger and constant 5V boost controller for mobile power supply. The charging part integrates functions such as high-precision voltage and charging current regulators, pre-charging, charging status indication and charging cut-off. Output maximum 1A charging current. The boost circuit adopts a VFM switching DC/DC boost converter with extremely low no-load current manufactured by CMOS technology. It has extremely low no-load power consumption (less than 10uA), and the boost output drive current capability can reach 1A. No need for external keys, plug and play.

The charging part is a linear step-down method, with a built-in PMOSFET and an anti-backflow circuit, so no external detection resistors and isolation diodes are required. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions, and the full voltage is fixed at 4.2V. The charge current can be set externally with a resistor. When the battery reaches 4.2V, the charging current gradually drops to 1/5 of the set current value, and the TP5410 will automatically terminate the charging. The boost part also has a built-in power NMOSFET, and the smaller internal resistance can provide driving energy up to 5V/1A. The higher integration level makes TP5410 work normally with only a small number of peripheral devices. TP5410 also integrates charging temperature protection, boost input power current limiting loop, can dynamically adjust current according to load conditions, and has fast response and overcurrent shutdown functions. The boost converter adopts the frequency conversion method, so it has extremely low no-load power consumption, ripple, stronger driving ability and higher efficiency than similar products at home and abroad.

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.

According to Japanese media, China ranks first in the world in the number of 5G standard-essential patents.

According to the "Nihon Keizai Shimbun" report on September 21, China's Minister of Industry and Information Technology Miao Wei revealed at a press conference on the 20th that China ranks first in the world in the number of 5G standard essential patents (SEPs). SEP is an essential patent for the manufacture of 5G products, a new generation of communication standards. Europe and the United States have mastered SEP in the 4G field, and China Huawei Technologies Co., Ltd. has mastered many 5G patents.

According to the report, regarding the relationship between the world's communication technology and China, Miao Wei pointed out that after "2G follow, 3G breakthrough", China has achieved a historic leap of "4G synchronization" and "5G leadership". He revealed that next year, China is expected to invest on a large scale in the construction of an independent 5G network. 5G networks are the infrastructure for developing next-generation industries such as artificial intelligence (AI).

According to statistics from the German Patent Investigation Company, the number of 5G patent applications in China accounts for 34% of the total number of applications in the world, ranking first. Miao Wei emphasized that China ranks first in the world in the field of SEP, which can better reflect the high-tech level.

The Chinese government issued 5G licenses to four state-owned telecommunications companies in June, the report said. The four companies cooperated with each other to promote the construction of 5G communication network while restraining the scale of investment. According to Miao Wei, there are more than 10 5G mobile phones commercially released in the Chinese market. According to government research institutions, 5G will bring huge economic benefits.
