Overview
Description
The DA9155M Performance Board is designed to evaluate the DA9155M slave battery charger. The optimized board layout enables testing at full-rated power and measurement of efficiency, current accuracy, transient response, and thermal performance.
The performance board includes an interface connector to the communication board referred as the Digital I/O (DIO) board. This DIO board connects the DA9155M to a computer via USB-to-I2C, for status monitoring and control using the DA9155M Graphical User Interface (GUI).
DA9155M offers a small solution that can be easily added on to existing main charger circuit designs and solves the heat dissipation problem created when the rapid charging feature is adopted in a system. It is compatible to all rapid charging technologies. DA9155M is added in parallel with the main battery charger to solve the thermal issue.
