describe

TP4100/TP4101 is a complete single-cell lithium-ion battery charge management and discharge protection chip, the first 5V power supply reverse polarity protection, with battery reverse polarity protection, compatible with 3mA-1000mA charging current. Its constant current/constant voltage linear control, thin DFN and TSOT packages and low external component count make it ideal for portable product applications.

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. The chip has an adaptive function of power supply voltage and power, and can directly draw power from USB or solar energy. The full voltage is fixed at 4.2V, while the charge current can be set externally with a resistor. When the battery reaches 4.2V, the charging current drops to 1/10 of the set value, and the TP4100 will automatically terminate the charging.

The discharge management of TP4100 includes under-voltage protection, over-charge protection, output short-circuit protection, output over-current protection, chip over-temperature protection and delayed self-activation recovery after various protections. Other features include charge current monitor, under-voltage lockout , automatic recharge, and two pins for indicating charge status (TP4101 has one charge indicating status pin). The TP4100 is packaged in an 8-pin DFN3*3 package with a charging current range of 3mA-1000mA. The TP4101 is packaged in a 6-pin TSOT23 with a charging current range of 3mA-600mA.

typical application

Precautions for TP4100/TP4101 Test Use

1. In order to ensure reliable use in various situations and prevent chip damage caused by spikes and glitches, it is recommended that 10uF ceramic capacitors and 0.1uF ceramic capacitors be used for Vcc and BAT in TP4100/TP4101 applications. All capacitors must be located close to the chip lead. The feet should not be placed too far. In the application of reverse power supply protection environment, it is required to use an application circuit with dissipation resistance and increase the input capacitance.

2. If you need to test the charging current of TP4100/TP4101, the BAT terminal of the chip should be directly connected to the positive pole of the battery, and the ammeter cannot be connected in series. The ammeter can be connected to the Vcc terminal of the chip.

Today (3), Huawei held the 5th Asia Pacific Innovation Day in Chengdu.

In the opening speech, Xu Wenwei, director of Huawei and dean of the Strategic Research Institute, announced that Huawei has won more than 50 5G commercial contracts worldwide, of which 28 are from Europe, 11 from the Middle East, 6 from the Asia-Pacific region, and 4 from the In the Americas, one is from Africa; more than 200,000 5G base stations were shipped, and nearly two-thirds of the 5G base stations were built by Huawei.

He also said that according to data at the end of 2018, China accounted for more than half of the world's 4G base stations, and 5G base stations would also account for more than half of the world's total. The future development of 5G depends on China.

In addition, Xu Wenwei said that with the advent of 5G, the limit of Shannon's Law has been reached, and Moore's Law has gradually reached its limit. Both the theoretical limit and the engineering limit need to break the bottleneck. Huawei also needs to move from innovation 1.0 to innovation 2.0, from innovation to invention. The most important of these is the university, and Huawei will fund university research.

Earlier, at the end of June, Ding Yun, Huawei's executive director and president of the operator division, said that so far, Huawei has won 50 5G commercial contracts worldwide, and the shipment of 5G equipment has exceeded 150,000 sets. The contracts come from South Korea, Switzerland, the United Kingdom, Finland and other countries, and two-thirds of the world's released 5G commercial networks are deployed by Huawei.
