    Datasheet Summary with AI

    # ETA6003: 2.5A, 3MHz Switching Charger with Dynamic Power Path Management

    ## Description

    ️· Switching Li-Ion battery charger with dynamic power-path control and input current limiting.
    ️· Regulates system voltage (VSYS) or pre-conditions/fast-charges battery based on battery voltage.
    ️· No external sense resistor required for current sensing.
    ️· Charging current programmable via ISET1/ISET2 pins, determined by USB_DET status.
    ️· Disconnects SYS to BATT when battery reaches 4.2V termination voltage.
    ️· Dynamic power path activates to supplement system load from battery when SYS load exceeds DCDC regulator's current limit.

    ## Features

    ️· Up to 95% DC-DC efficiency
    ️· 50mΩ Power Path MOSFET
    ️· Up to 2.5A max charging current
    ️· Instant-on functionality with dead or absent battery
    ️· No battery detection required
    ️· Programmable USB and AC IN charging current

    ## Applications

    ️· Tablets & MIDs
    ️· Smartphones
    ️· Power Banks
