Power management integrated circuit (PMIC) devices are responsible for controlling and optimizing the power performance in modern electronic systems. The DS2762BE+, a battery monitor and protector, is an example of such a PMIC device designed to target applications including smart phones, two-way radio systems, tablets, wearable devices, and industrial systems. This article will discuss the DS2762BE+’s application field and working principle.The DS2762BE+ is a battery monitoring solution that can monitor up to two battery cells, with a wide (20mV to 5V) input voltage range and a maximum power input of 8A per channel. Its versatile and highly accurate monitoring technology provides exceptional protection against overvoltage, undervoltage, over-temperature and under-temperature conditions. The device also offers active balancing, precharge, and cyclic refreshers for improved reliability and battery life. Additionally, the device can provide, operating information such as Remaining Battery Capacity, SoC, SoH and CPS using a coulomb counter and voltage/temperature monitors.The DS2762BE+ is composed of analog and digital circuitries, which allow it to interact with both digital and analog components. The analog circuitry is utilized to sense the voltage, current, and temperature of the battery while the digital circuitry acts as the control and processing module. This digital circuitry uses its power management modules to control the charging current and other system parameters. Furthermore, the on-chip SPI interface allows external control over the system’s parameters.The application field of the DS2762BE+ is the extended battery life of high-performance portable devices such as two-way radio systems, tablets, and wearable devices. This device can be used to ensure a longer life cycle for the battery, as well as safeguard against any abnormalities or malfunctions in the battery. It can also be used for systems that require an uninterrupted power supply such as industrial automation or medical equipment.In terms of its working principle, the DS2762BE+ can accurately monitor the voltage, temperature, and current of a battery. By using its analog circuitry to detect these parameters, the device can detect under-voltage, over-voltage, over-temperature and under-temperature conditions. The on-board digital circuitry then processes this data to determine the battery’s State of Charge (SoC), State of Health (SoH), and charge capacity. Based on this data, the digital circuitry can then control the charging current and system parameters.The DS2762BE+ also offers additional features such as cycle refreshers, active balancing, precharge, and data logging for analysis. The refresher feature allows the device to cycle charge and discharge the battery in order to maintain a better condition. The active balancing feature allows the device to discharge cells with higher voltage levels than others, which in turn prevents overcharging of cells and improves the overall battery performance. The device also provides data logging of the battery’s operating parameters, which can be used to analyse the performance and behaviour of the device.In conclusion, the DS2762BE+ is an advanced PMIC battery monitor and protector device designed for applications needing extended battery life such as two-way radio systems, tablets, and wearable devices. This device can accurately monitor the voltage, temperature, and current of the battery and provides features such as active balancing, precharge, and data logging. With its highly efficient and accurate power management technology, the DS2762BE+ can help improve the performance and reliability of the battery and the attached device.
