Controller IC Chip - MOSFET ETA6003Q3Q ETA6003 ETAG003 ETA-42 QFN-16 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.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
