ETA6002
2.5A, 3MHz Switching Charger with Dynamic Power Path in ESOP8
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.
