With the increasing diversification of portable electronic devices and the continuous improvement of overall performance, overall power consumption is also facing greater challenges. The most direct and effective way is to increase the capacity of the battery to increase the service life of the entire machine. In order to not reduce the user experience, faster and more effective charging solutions are needed to reduce charging time.

To this end, Xindao Technology has launched a single lithium-ion charging chip that can support 3A charging current to meet the needs of customers to shorten charging time.

PSC2965 is a highly integrated single section lithium-ion digital analog hybrid charging chip. It adopts an efficient inductive switch architecture and is widely used in electronic devices such as smartphones, tablets, MiFi, and smart speakers.

1、 PSC2965 Key Parameters

• Supports a maximum charging current of 3A, and the efficiency of 2.5A charging current can reach 91%.
  Supports an input working voltage of 3.9V~14V and a maximum DC withstand voltage of 20V, and can support most common and fast charging adapters on the market.
  Supports a charging voltage of 3.8V~4.464V (programmable), which can meet almost all specifications of single lithium-ion batteries on the market.
  Having high precision charging parameters (± 0.5% charging voltage; ± 5% charging current; ± 10% cut-off current).

2、 PSC2965 Key Features

Support dynamic power management (VINDPM, INDPM) to meet the output power requirements of different adapters.

Support for path management function: Unlike traditional lithium-ion battery charging chips, PSC2965 can achieve path management function by adjusting the Battery FET between the integrated system of the chip and the battery:

• By programming to turn off the Battery FET at the factory, the power consumption of electronic devices is greatly reduced, allowing the battery level to remain high even after long-distance transportation and long-term storage.
  After inserting the charger, it can ensure that the minimum voltage at the system end is not less than 3.5V (programmable) when the battery is over discharged or not in place, so that electronic devices can support low battery fast startup and battery free operation.
  By pressing the button (connected to the QON pin of the chip), hardware reset and restart can be performed after the system crashes.
  After the battery is fully charged, the power consumption of the system can be taken from the power supply end, greatly reducing the number of battery recharges and thus improving the battery’s service life.

Supports a universal IIC communication interface, with a total of more than ten registers open for users to read and write configuration of charging and discharging related parameters. This includes DPMs with multiple levels of configurable input voltage and current, charging current and charging voltage with multiple levels of configurable settings, cutoff current, and so on.

Supports reverse boost function, providing stable power supply of around 5V for USB OTG mode of devices:

In addition, PSC2965 supports comprehensive multiple protection machines, including programmable JEITA, as well as overvoltage, undervoltage, overcurrent, short circuit, and over temperature protection.
