DESCRIPTION

programming ISET pin. When the battery voltage reaches the

ETA6102 is a switching Li-Ion battery charger with dynamic

power-path control and input current limiting.

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 V_BATT, ETA6102 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 (V_SYS) to

a preset voltage. It does not require an external sense resistor
