(Low-cost synchronous 3A lithium battery charging, 5V3A boost, display, battery protection)

Overview

TP5602 is a fully integrated function mobile power dedicated VLSI, specially designed for medium and high power mobile power. Internally integrates automatic charging management and battery isolation PMOS2, boost management, power display, battery protection and other functions into a single chip, plus an input isolation PMOS1, a power NMOS1, an inductor, and a small number of RC components, the application circuit is simple , stable and reliable performance, debugging-free mass production, high efficiency and high yield.

TP5602 adopts unique single-inductor multiplexing technology, built-in high-efficiency synchronous step-down 4.2V3A lithium battery charging circuit and synchronous boost 5V 3A output circuit; 4-channel LED display output can display the power during charging and discharging in 5 segments, which can be applied to Red, green and blue LEDs are directly driven, and are also used for abnormal state alarm display; no external battery protection circuit is required, and various input and output protections of the battery are integrated inside (overvoltage, overcharge, undervoltage, overcurrent, short circuit, etc.);

TP5602 provides function settings: plug-in automatic charging, button boost, light load automatic shutdown (when boosting); step-down charging constant current adjustable; 5V boost output constant current adjustable externally. Its ultra-small QFN24 package and simple peripheral circuits make the TP5602 ideal for high-power stand-alone charging or stand-alone boost management applications for other portable devices.

TP5602 has a wide input voltage (4.2-7V MAX), and is protected against reverse connection of the power supply. When charging, charging the battery is divided into three stages: trickle precharge, constant current, and constant voltage. The trickle precharge current and constant current charging current are both Adjusted by an external resistor, the maximum charging current is 3.5A. 4LED different display modes when charging different battery voltages. The switching operation mode of the charging switching frequency of 700KHz makes it possible to use smaller peripheral devices and maintain a small heat generation during high current charging.

TP5602 has a built-in 4.25V VIO charging adaptive circuit. When the VIO current is not driven enough to cause the VIO to drop to 4.2V, the internal charging current will be automatically reduced. Users do not have to worry about the problem of low-power USB ports, power supplies or adapters due to excessive current settings.

TP5602 has built-in anti-battery backflow PMOS2 circuit, so peripheral protection such as anti-backflow Schottky diode is not required.

The TP5602 synchronous boost circuit can output constant voltage and current limit, the voltage is internally fixed at 5V, and the current can reach 3A. The current limit value can be adjusted by an external setting (VIlmt) to limit the output current of the battery terminal, thereby controlling the VIO output power.

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.

When TSMC's 7-nanometer production capacity is full, the 5-nanometer layout is also a good news. With five major customers, Apple, HiSilicon, Supermicro, Bitmain, and Xilinx all deciding to adopt 5nm as the next-generation main chip process, TSMC's 5nm demand exceeded expectations, and the production capacity was significantly increased from the original monthly plan. The number of 51,000 pieces has greatly increased to 70,000 pieces, an increase of nearly 40%. At the same time, the pace of mass production has been accelerated, and mass production will be carried out in March next year.

TSMC has achieved a complete lead in the industry in 7nm. In addition, the demand for 5nm exceeds expectations. The legal person is optimistic that TSMC's advanced manufacturing process will continue to dominate the foundry industry, greatly expanding the gap with rivals such as Samsung and Intel. With the simultaneous increase in volume of 7nm and 5nm, next year's operations will once again show a strong growth trend, challenging the ninth consecutive year to record highs.

TSMC Chairman Liu Deyin officially revealed to the world at the Taipei International Semiconductor Exhibition Technology Think Tank Leaders Summit last week that TSMC's 5nm has stepped out of the research and development stage and is actively preparing to enter mass production. A year of rapid expansion and a new record. However, TSMC did not comment on the status of customers and orders.

Affected by the U.S.-China trade war, TSMC’s 5-nanometer production capacity layout was stagnant for a time. As countries successively accelerated the pace of 5G deployment, simultaneously driving demand for artificial intelligence (AI) and high-speed computing chips, related chip factories actively adopted TSMC’s 7-nanometer process and drove The speed of these big factories entering the 5-nanometer process has enabled TSMC to restore the momentum of 5-nanometer production capacity deployment, and even faster layout, injecting strong growth momentum into next year's performance.

TSMC supply chain said that TSMC's main customers have accelerated the pace of introducing 5nm, not only Apple has restored the original production capacity, but HiSilicon has also begun to have in-depth cooperation with TSMC in 5nm due to Huawei's acceleration of the launch of 5G base stations and mobile phones.

In addition, through the cooperation with TSMC 7nm, Supermicro has achieved good sales of its central processing units and graphics chips. In addition, Bitmain has also adopted 5nm in order to seize AI business opportunities. At the same time, it has continued to shine in AI special application chips. The programmable logic element (FPGA) of Xilinx has also continued to advance to 5nm, prompting TSMC's 5nm process demand to exceed expectations.

In response to strong customer demand, TSMC has decided to expand the 5nm production capacity to 80,000 wafers if necessary, and the expansion is concentrated in the P3 plant of Nanke Fab 18.
