ETA6002
2.5A, 3MHz Switching Charger with Dynamic Power Path in 8-pin ESOP
for current sensing. The fast-charging current is determined by

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.
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
