DESCRIPTION
ETA6002 is a switching Li -Ion battery charger with dynamic power-path control and input current limiting. When a battery is connected, depending on the battery voltage, the DC -DC switching regulator either pre -conditions, fast - charges the battery or just regulates a system voltage (V SYS) to a preset voltage. It does not require an external sense resistor for current sensing. The fast-charging current is determined by programming ISET pin . When the battery voltage reaches the termination voltage i.e. 4.2V, the charging path disconnects SYS to BATT. The ETA6002 also includes a dynamic power path when the SYS load current exceeds current limit of the DCDC regulator internally set, the SYS voltage falls below VBATT, ETA6002 turns on the power -path to supplement the system load through the battery.
