钰泰 ETA4098FQFJ 可编程1节锂电池充电器

　　DESCRIPTION

　　The ETA4098 is a flexibly programmable highly- integrated single cell Li-lon 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.The charge current and charge termination current are programmable by flexible external resistors.

　　The power path management function features a low dropout regulator from the input to the system and a low Rdson switch from the battery to the system, ensuring the continuous power supply to the system.

　　ETA4098 is available in a FCQFN-9L package.
