USB Power Manager with
High Voltage Switching Charger
The LTC
®
4089/LTC4089-5 are USB power managers plus
high voltage Li-Ion battery chargers. These devices control
the total current used by the USB peripheral for operation
and battery charging. Battery charge current is automati-
cally reduced such that the sum of the load current and
the charge current does not exceed the programmed input
current limit. The LTC4089/LTC4089-5 also accommodate
high voltage power supplies, such as 12V AC-DC wall
adapters, Firewire, or automotive power.
The LTC4089 provides an adaptive output that tracks the
battery voltage for high effi ciency charging from the high
voltage input. The LTC4089-5 provides a fi xed 5V output
from the high voltage input to charge single cell Li-Ion
batteries. The charge current is programmable and an
end-of-charge status output (CHRG) indicates full charge.
Also featured is programmable total charge time, an NTC
thermistor input used to monitor battery temperature while
charging and automatic recharging of the battery.
