The DS1259SN is a Smart Battery Management IC (SBMIC) that is part of a complete family of ICs used to implement a very sophisticated charging, balancing, and powering of rechargeable batteries through a so-called Battery Management System (BMS). This system allows designers to develop an integrated platform for managing the use of a rechargeable battery both at the system level and at a component level. The DS1259SN is specifically designed to be an intelligent platform for managing a single cell rechargeable battery system, creating optimal charging and power modes while still providing excellent protection to the battery itself.

The primary features of the DS1259SN include a complete range of charging and power control, as well as battery protection. The SBMIC takes the information it receives from a remote master controller, such as an MCU, and uses this data to control the charging and balancing of a single cell rechargeable battery. The DS1259SN also offers an embedded fuel gauge and voltage regulator, as well as a highly efficient switching power supply.

In addition to taking input from an external controller, the SBMIC also provides information about the condition of the cell to the system. This information, combined with the other data from the controller, allows the system to understand the specific usage and charging history from each individual cell. With this information, designers can better optimize the performance of the overall battery system.

The DS1259SN offers several charging profiles, depending on the state of charge. For example, the standard profile allows for charging up to the maximum allowed current, and then quickly shifting the charging to trickle charge when the voltage is reached. Other profiles include high-current fast charging, low-current trickle charging, and a custom profile. In addition, the charge regulator can be configured to sleep between charge cycles, allowing the maximum capacity of the battery to be maintained.

The DS1259SN is designed to intelligently balance the cells, while avoiding overcharging and overdischarging. At the system level, the SBMIC can detect when a cell is unbalanced and autonomously shift charging current between cells to ensure all of them reach the same voltage. At the component level, the DS1259SN can detect when a single cell is no longer usable, and shut down the charging process.

The DS1259SN is also designed with a robust set of protection features. These features include overcurrent, overvoltage, undervoltage, and overtemperature protections, all of which are designed to help protect the battery from damage due to excessive usage. The battery protection features also provide information to the controller, allowing the system to take steps to rectify any issues.

The DS1259SN is an ideal choice for designers developing a BMS for managing a single cell rechargeable battery system. The SBMIC enables designers to easily implement a complete system for maintaining maximum battery performance, while providing excellent protection of the cells. With its powerful protection, charge control, and fuel gauge capabilities, the DS1259SN provides an integrated platform for a complete battery management system.
