The DS2764AE+T&R device is part of a family of Power Management Products (PMIC) that is part of the Battery Management Solutions product line by Dallas Semiconductor. This device provides a reliable system for monitoring and controlling the charging and discharging process of a battery pack, ensuring optimal battery efficiency and safety. It is specifically designed for the latest lithium-ion battery packs.

The DS2764AE+T&R device integrates an on-chip full-duplex I2C/SMBus interface and advanced security protection functionality. It has a wide input voltage range of 1.71-5.5V, which is much wider than many other PMICs. The specific features of the device include a True Temperature Update (TTUTR) algorithm to protect the battery pack from high temperatures, an operating temperature range of -40°C to 105°C, a 12-bit ADC, a low-voltage indicator, an automatic cell balancing feature, and support for long battery-discharge cycles.

The DS2764AE+T&R device can be applied in portable medical, video and audio products, wearables, and other high-performance and energy-efficient applications. The life and performance of portable devices can be improved with this device, as it monitors and optimizes the operation of the battery pack. This device offers a reliable and cost-effective solution for managing the charging and discharging of a battery pack.

The working principle of the DS2764AE+T&R device is quite simple. It monitors the temperature, voltage and current of the battery pack, and adjusts the charging and discharging process according to the parameters. It also has a True Temperature Update (TTUTR) algorithm which protects the battery pack from high temperatures. The device also has an automatic cell balancing feature, which adjusts the voltage of the cells to ensure uniform charging and discharging of the battery pack.

In addition, the device has a low-voltage indicator, which provides an audible and visual alert when the battery is near empty. This feature helps to prevent battery depletion and reduce the risk of system failure due to low voltage. It also has a 12-bit ADC which makes precise measurements of current, voltage and temperature.

The DS2764AE+T&R device is a key component of power management systems for devices using lithium-ion batteries, offering enhanced safety, reliability, and performance. It eliminates the need for multiple PMICs and enables the efficient management of battery packs in a broad range of applications. It is ideal for portable medical, video and audio products, wearables, and other high-performance and energy-efficient applications.
