TP4065-A Tuowei 3mA-600mA linear lithium-ion battery charger advantage product

TP4065

3mA-600mA Linear Li-Ion Battery Charger

Product introduction

TP4065 is a complete single-cell lithium battery charger, the world's first single chip with battery reverse polarity protection, input power supply reverse polarity protection, compatible with 3mA-600mA charging current. With trickle, constant current, and constant voltage control, the SOT23-5 package and low external component count make the TP4065 ideal for portable applications. TP4065 can work with USB power and adapter power.

External sense resistors and blocking diodes are not required due to the use of an internal PMOSFET architecture, coupled with a reverse charge protection circuit. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions. Full voltage 4.2V. The charge current can be set externally with a resistor. When the battery reaches the preset voltage, the charging current drops to 1/10 of the set value, and the TP4065 will automatically terminate the charging.

When the input voltage (AC adapter or USB power supply) is removed, the TP4065 automatically enters a low current state and the battery leakage current is less than 1μA. Other features of the TP4065 include power supply adaptation, undervoltage lockout, automatic recharge and a pin to indicate charge status.

On May 13, according to foreign media reports, chip foundry TSMC has been at the forefront of the industry in chip technology in recent years. After taking the lead in mass production of the 7nm process in 2018, the 5nm process has also been mass-produced this year.

Advanced technology has also brought a large number of orders to TSMC. Apple, Huawei, Qualcomm, Nvidia and other companies are all TSMC customers.

Recently, a list of customers of TSMC's 5nm process has been exposed, including the name of the customer company and the specific chips that TSMC will manufacture for it.

Judging from the exposed list, the 5nm process mentioned by TSMC, including the 5nm process N5 and the enhanced version of N5+, covers the time period of 2020, 2021-2022.

In 2020, that is, this year, TSMC will only mass-produce 5nm chips for two companies, namely Apple and Huawei HiSilicon. The former is A14 and A14X processors, and Huawei HiSilicon is Kirin 1000 and network processors.

In 2021-2022, more customers and products will be mass-produced. In addition to Huawei and Apple, there are currently six exposed, namely AMD, Broadcom, Qualcomm, NVIDIA, MediaTek and Intel.

However, judging from the exposed list, its chips that will be mass-produced in 2021-2022 may only be before 2022, or at the beginning of 2022, because the Apple product listed during this period is A15, while Apple's A series The processor is updated every year, and the A16 will be launched in 2022, and mass production will begin at the end of the first quarter and the beginning of the second quarter.
