ETA6003

2.5A, 3MHz Switching Charger with Dynamic Power Path Management

DESCRIPTION

ETA6003 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 (V_SYS) to a preset voltage. It does not require an external sense resistor for current sensing. The charging current is determined by

programming ISET1 or ISET2 pin, depending on the state of the USB_DET. If USB_DET is low, indicating an valid AC adapter input is present,

the charge current is set by ISET1; otherwise, it is set by ISET2. When the battery voltage reaches the termination voltage i.e. 4.2V, the

charging path disconnects SYS to BATT. The ETA6003 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, ETA6003 turns on the power-path to supplement the system load

through the battery.
