Working Principles

The LTC4059AEDC#TRPBF operates based on a constant-current/constant-voltage charging algorithm. It starts by delivering a constant current to the battery until the charge termination voltage is reached. At this point, the charger switches to a constant-voltage mode, maintaining the battery voltage at the termination level while reducing the charging current. Once the charging current drops below a certain threshold, the charger enters a standby mode.

Detailed Application Field Plans

The LTC4059AEDC#TRPBF is widely used in various portable electronic devices, including: - Smartphones - Tablets - Portable media players - Bluetooth headsets - GPS devices - Wearable devices
