The S-8261ABKMD-G3KT2U is a state of the art linear battery management (BMS) system part of the Shimizu Corporation’s power management integrated circuit (PMIC) family. This specific device is designed to be an all-in-one battery management solution that can be used to replace multiple components in a system. Few of the features offered by this device include an adjustable buck-boost converter, battery float and trickle charge circuits, voltage monitoring, current sensing, temperature sensing and auxiliary startup supply circuit.

An important aspect to consider when selecting any power management integrated circuit (PMIC) device is the application field it is intended for. The S-8261ABKM-G3KT2U was specifically designed to be used in applications such as instrumentation and telecom systems, unmanned aerial vehicles, unmanned ground vehicles, remote navigation systems, and even certain medical electronic applications. It can also be used as a power source in various consumer electronics products, such as portable speakers and set top boxes.

Now let’s explore the working principle of the S-8261ABKM-G3KT2U battery management system. The main purpose of any BMS system is to properly manage and discharge the cells of a given battery pack. It is also responsible for optimizing battery performance and lifespan. To do so, the S-8261ABKM-G3KT2U utilizes two main pieces of technology; the first being a dedicated voltage monitor which keeps track of individual cell voltages in order to detect any fault conditions. The second is a buck-boost converter which can be adjusted to provide the necessary current to the cells based on their respective voltages. Furthermore, the device can also be used to monitor the temperature of the battery pack and provide additional protection against over-temperature conditions.

Now let’s look at some of the main features of the S-8261ABKM-G3KT2U. The device is equipped with a voltage monitor which can measure up to three separate cell voltages with an accuracy of 6.25mV. This allows the user to configure different thresholds for each cell in order to detect any over- or under-voltage conditions. Furthermore, the device is also capable of performing a “cell balancing” operation, in which the output of the buck-boost converter is modulated in order to keep all cells at the same level. The integrated trickle charge circuit can also be used to automatically recharge the battery when necessary.

The S-8261ABKM-G3KT2U is also equipped with a number of protection mechanisms to ensure the safety of the user and the device itself. It is equipped with over-temperature and over-current protection circuits which automatically shut down the device when triggered. It is also equipped with an auxiliary startup supply circuit which provides low-voltage power when the battery voltage is too low to support the normal operation of the device.

The S-8261ABKM-G3KT2U battery management system provides an all-in-one solution for various battery-powered applications. With its voltage monitoring, buck-boost converter, temperature sensing, current sensing and auxiliary startup supply features, this device provides a comprehensive system for optimally managing any battery pack and ensuring its safe operation. As such, it is an ideal component for any PMIC - Battery Management system.
