DESCRIPTION
Furthermore, the ME4054 is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture.Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. When the input supply (wall adapter or USB supply) is removed, the ME4054 automatically enters a low current state, dropping the battery drain current to less than 2µA.The ME4054 can be put into shutdown mode, reducing the supply current to 25µA. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presence of an input voltage. w VÛm `R●yÑb € of w.g ww otec h.co m FEATURES
