MAX20094/MAX20095 CC/CV Battery Chargers Analog Devices Inc. MAX20094/MAX20095 CC/CV Battery Chargers provide a high-efficiency synchronous boost controller to supply critical systems in the event the primary power source is lost. The configurable constant-current/constant-voltage (CC/CV) battery charger offers diagnostic features to check battery state-of-health (SOH) and IC functionality. Charging thresholds and boost output voltage are configurable to support popular battery chemistries and a wide range of cell counts.
