Battery Management Solutions

Effective battery management is more important than ever as portable applications extend into more industries. The demand for small, low-cost products with long battery life is increasing. Our industry-leading battery management solutions include battery chargers, fuel gauges, battery monitors, battery selectors, and battery protectors—solutions that reduce cost, save space, and significantly extend the battery life of portable products.

Our fuel gauges monitor remaining battery charge using the proprietary ModelGauge™ algorithm to provide the highest accuracy. SHA-256 authentication helps to prevent battery pack cloning. Our battery charger ICs provide support for USB Type-C devices, meeting all Power Delivery (PD) 3.0 voltage range specifications. Together, our battery chargers and fuel gauges provide the efficiency, accuracy, and protection required to support Li+ battery applications.
