The LX2202 Linear Battery Charger is a multi-state (2 stage) Li-Ion battery charger (Constant current / Constant voltage) that is designed to minimize battery charge time (even from current limited sources such as USB) and provide a simplified interface to control battery discharge. LX2202 features up to 2A charging current from an AC adapter and an isolated battery topology to minimize charge time from current limited sources such as USB. A thermal control loop maintains a safe operating temperature at all times.
