SM6780AS NIPPON PRECISION CIRCUITS INC. Ni-Cd/Ni-MH Battery Charger IC OVERVIEW 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), .
