DA9318M Overview
DA9318L/M is a direct charger using a high-efficiency current doubler with integrated Analog to Digital Converter (ADC) for system monitoring. The device is especially optimized to handle high charging currents and at the same time ensure the safety of the battery and the system. It operates together with a main charger, which handles the pre-charge and constant voltage charging duties.
