ETA ETA6002
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 (VSYS) to a preset voltage. It does not require an external sense resistor for current sensing.| Part No. | ETA6002 |

DESCRIPTION
FEATURES
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 (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., 4.2V, the charging path Switching Charger with Power Path Management Up to 95% DC-DC Efficiency 50mΩ Power Path MOSFET Up to 2.5A Max charging current Instant on with a dead Battery or no Battery No Battery Detection No External Sense Resistor Programmable Charging Current RoHS Compliant 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 powerpath to supplement the system load through the battery.
