Description
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.
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. The LX2202 provides a seamless complete battery interface. When the input power source is removed, the LX2202 provides the discharge path for the battery with extremely low discharge impedance. This eliminates the need for external discharge switch and voltage supervisors. In USB.
