Controller IC Chip - MOSFET ETA6003Q3Q ETA6003 ETAG003 ETA-42 QFN-16 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0419)
2.5A, 3MHz Switching Charger with Dynamic Power Path Management
ETA6003is 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 charging current is determined by programming ISET1 or ISET2pin, depending on the stateof the USB_DET. If USB_DET is low,indicating an valid AC adapterinputis present,the charge current is set by ISET1; otherwise, it is set by ISET2. When the battery voltage reaches the terminationvoltage i.e. 4.2V, the chargingpath disconnects SYS toBATT. The ETA6003 also includes a dynamic power path when the SYS load current exceeds current limitof the DCDC regulator internally set, the SYS voltage falls below VBATT, ETA6003turns on the power-path to supplement the system load through the battery.
