DESCRIPTIO
The LTC
operation of portable USB 1.0 and 2.0 compliant devices
while they are connected to a USB port. As the USB periph-
eral 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
