The PS4160EV Evaluation Kit provides the opportunity to evaluate the PS401 IC quickly and easily. The evaluation kit contains all of the hardware and software necessary to implement a fully functional smart battery and demonstrate all operating modes. The included PS4160 module is a complete smart battery controller subsystem, based on the Microchip PS401 battery manager with patented Accuron™ technology. The module is designed to operate in a battery pack consisting of three (3) and four (4) series connected Li-based cells. The module consists of the Microchip PS401 battery manager IC, with a four LED SOC display, safety circuit, and an optional connection for an external thermistor. The included PowerTool™ Windows®-based software can be used to modify the programming in the preprogrammed evaluation module. Although many interdependent parameters must be taken into account when programming the battery manager, the process is simplified with the PowerTool configuration wizard.
