特点Manages Total Power Between a USB Peripheral and Battery ChargerMinimal Voltage Drop (100mV at 500mA)Ultralow Battery Drain: 1μAReverse Current Blocking Diode not RequiredUndervoltage LockoutVery Few External ComponentsCompatible with Several LTC Linear Battery ChargersOvertemperature ProtectedDual Battery Charge Priority ManagementLow Profile (1mm) SOT-23 Package典型应用典型应用描述The LTC?4410 enables simultaneous battery charging and operation of portable USB 1.0 and 2.0 compliant devices while they are connected to a USB port. As the USB peripheral load increases, the LTC4410 proportionally reduces the battery charge current to keep the total current less than 500mA or 100mA, depending on the state of the MODE pin.The LTC4410 includes a USB present output that drives an external P-channel MOSFET to disconnect the battery from the USB peripheral when the USB power is valid. This allows device operation when connected to the USB port, even when the battery is deeply discharged.Other features include reverse current blocking, thermal shutdown and low quiescent current (80μA in 500mA MODE) that is compliant with USB Suspend Mode.The LTC4410 is available in the low profile (1mm) SOT-23 (ThinSOT?) package.
