ETA ETA4098
The ETA4098 is a flexibly programmable highlyintegrated single cell Li-Ion and Li-polymer battery charger with power path management. It features pre-charging, fast charging(CC) and constant voltage(CV) charging, end-of charging termination, and auto-recharge. The built-in safe-timer monitors input voltage, input current, chip temperature, external temperature and load current, preventing from being damaged due to excessive high current and over-discharging.| Part No. | ETA4098 |
