As a multi-purpose power management integrated circuit (PMIC), the DS2726G+T&R(herein referred to as “DS2726G+”) is a high efficiency, low power device that can be used to manage multiple application fields and batery types. It is the first generation of integrated voltage regulator and temperature protection device and can be used to improve system reliability and flexibility.

The DS2726G+ belongs to PMIC - Battery Management category. It is a comprehensive single-chip power management solution with overload current protection, over temperature protection, reverse battery protection, and overvoltage protection. It is designed for applications such as charging, monitoring, controlling and protecting various types of lithium ion (Li-ion) and nickel-metal hydride (NiMH) batteries. It can be used for automotive and industrial applications, as well as for consumer electronics.

The DS2726G+ features several system peripheral components including hysteretic pulse-width modulation (H-PWM) output voltage control, overvoltage protection (OVP), undervoltage protection (UVP) and an on-chip analog temperature sensor. The device also includes an integrated RISC-based microcontroller and a 5-port digital I/O to enable full customization of the application.

The working principles of DS2726G+ are based on two main components, the control logic and the output power stage. The control logic is responsible for monitoring and controlling the output voltage, current, and temperature. It is capable of charging, discharging, and balancing the battery cells, while monitoring their voltage and temperature. The output power stage consists of MOSFETs, which provides the current necessary to charge or discharge the battery cells.

The DS2726G+ is capable of detecting battery voltage, current and temperature, and providing a range of output voltages from 2.5V to 8.0V. It can support three charging modes, namely constant-voltage (CV), constant-current (CC), and constant-temperature (CT). The device also features a programmable over voltage protection (OVP) to protect against overcharging. Additionally, the device can detect both over temperature and over current and shut off the output of the battery when either threshold is exceeded.

The DS2726G+ contains a powerful, yet intuitive programming interface. Its many configurable parameters, including the charging mode, output voltage and current limit and temperature limit, as well as over-voltage and over-current protections, all make it easy to customize the application. Additionally, the device is available in a variety of packages that offer design flexibility in order to fit into different application landscape.

In conclusion, the DS2726G+ is an ideal solution for power management in a variety of applications. Due to its robust feature set, the device can be used for both automotive and consumer applications, and it provides superior power and temperature management. Furthermore, its easy to use programming interface makes it easy to customize the featureset for any particular application.
