TP54001A Lithium battery charging and 5V/1A boost control chip

describe

TP5400 is a single-cell lithium-ion battery charger and constant 5V boost controller dedicated to 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 TP5400 will automatically terminate the charging. The boost part also has a built-in power NMOSFET, and the smaller internal resistance can provide a driving capacity of 5V/1A. The higher integration level makes the TP5400 work normally with only a small number of peripheral devices. TP5400 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.

Features

★Programmable charging current up to 1000mA typical, up to 1.2A;

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.

Yang Zhuxiang, general manager of Hon Hai's panel factory Innolux, said that in the 2020 Tokyo Olympics and Paralympics, Japan's NHK will drive the "full ultra-high-definition generation" and accelerate the gathering of the global 8K ecosystem. In other words, last year was the budding year of 8K, and 2020 will It is the year of 8K take-off, and we will try our best to seize the business opportunities of 8K displays.

On the 19th, Yang Zhuxiang attended the "2019 DATE SUMMIT Digital Business Trend - International Forum" by the Foreign Trade Association and expressed the above views. Innolux was also present at the conference by splicing 4K video walls, the world's largest 120-inch 8K TV, 8K miniLED and Megazone TV to create an ambition to attack the 8K market.

Yang Zhuxiang pointed out that starting from the second quarter of this year, a number of 8K chip factories will be equipped with 4KTV SOC (system of chip) to form an 8K solution. It is estimated that from the fourth quarter of 2019 to the first half of 2020, the 8K supply chain will increase from Panel factories, key component suppliers and brands will gradually become complete.

Yang Zhuxiang said that Innolux’s 8K TVs are mainly 65-inch and 85-inch. Recently, the world’s highest-standard 120-inch 8K TV has attracted international attention. It is expected that there will be explosive growth in the shipment of 8K modules and complete sets in 2020-2021. In response to the diversification trend of the display field, Innolux's kirameki 8K public display is mainly for international airports and boutique department stores, and plans to launch it in the second quarter of next year with strategic partners.

In addition, Innolux's AM miniLED 8K public displays, with their seamless splicing and wireless extension variability, target medium and large-scale international exhibition venues/conferences or any commercial venues, and have been shipped in June this year. 8K Megazone technology is superior to OLED high-definition performance, affordable price, and active marketing layout with brand customers.

Yang Zhuxiang said that the 5G+8K ecosystem is not only a visual enjoyment of hardware and software integration, but also makes future smart life more exciting than imagined. Innolux hopes to enable consumers to embrace 8K and enjoy innovative smart life.
