LTC4090-5 Datasheet Usb Power Manager

Manufacturer: Linear Technology (now Analog Devices)

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.
