Manages Total Power Between a USB Peripheral
and Battery Charger
Minimal Voltage Drop (100mV at 500mA)
Ultralow Battery Drain: 1 μ A
Reverse Current Blocking Diode Not Required
Undervoltage Lockout
Very Few External Components
Compatible with Several LTC Linear Battery Chargers
Overtemperature Protected
Dual Battery Charge Priority Management
Low Profile (1mm) SOT-23 Package
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 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.

shutdown and low quiescent current (80 μ A in 500mA
MODE) that is compliant with USB Suspend Mode.
The LTC4410 is available in the low profile (1mm) SOT-23
(ThinSOT TM ) package.
