TP5100

TP51002A switch step-down 8.4V/4.2V lithium battery charger chip

Overview

TP5100 is a switching step-down dual-cell 8.4V/single-cell 4.2V lithium battery charge management chip. Its QFN16 ultra-small package

With simple peripheral circuits, the TP5100 is ideal for high-current charge management applications in portable devices. Meanwhile, TP5100

Built-in input overcurrent, undervoltage protection, chip overtemperature protection, short circuit protection, battery temperature monitoring, battery reverse connection protection.

TP5100 has a 5V-18V wide input voltage, and the battery charging is divided into three stages: trickle precharge, constant current, and constant voltage.

The pre-charging current and constant-current charging current are adjusted by external resistors, and the maximum charging current is 2A. TP5100 adopts frequency 400kHz

The switching mode of operation allows the use of smaller peripheral devices and still maintains a small amount of heat during high-current charging.

TP5100 has built-in power PMOSFET and anti-backflow circuit, so peripheral protection such as anti-backflow Schottky diode is not required.

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.
