FEATURES
LTC4090/LTC4090-5 USB Power Manager with 2A High Voltage Bat-Track Buck Regulator DESCRIPTION
The LTC®4090/LTC4090-5 are USB power managers plus high voltage Li-Ion/Polymer battery chargers.
The devices control the total current used by the USB peripheral for operation and battery charging. Battery charge current is automatically reduced such that the sum of the load current and the charge current does not exceed the programmed input current limit. The LTC4090/LTC4090-5 also accommodate high voltage power supplies, such as 12V AC/DC wall adapters, FireWire, or automotive power. The LTC4090 provides a Bat-Track adaptive output that tracks the battery voltage for high efficiency charging from the high voltage input. The LTC4090-5 provides a fixed 5V output from the high voltage input to charge single cell Li-Ion bateries. The charge current is programmable and an end-of-charge status output (CHRG) indicates full charge. Also featured are programmable total charge time, an NT
