ETA6102
ETA6102 is 3MHz Switching Charger manufactured by ETA.
DESCRIPTION
ETA6102 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, fastcharges the battery or just regulates a system voltage (VSYS) 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. 4.35V, the charging path disconnects SYS to BATT. The ETA6102 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, ETA6102 turns on the power-path to supplement the system load through the battery.
