Description

The SM6780AS is a quick charge control IC for Nickel-Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) rechargeable batteries. It supports quick charge, supplemental and pulse trickle charging modes. The charging mode is selected automatically in response to the battery voltage, temperature and charging time.

The quick charge uses either negative delta voltage detection (-V), temperature detection (T/t), or charging time cutoff to control the charging process. In addition, the quick charge mode can be placed on hold, if the battery voltage or battery temperature are abnormal, until normal conditions are restored.

The SM6780AS requires few external components to realize a high-stability quick charge battery charger.
