LTC4090-3 Datasheet Usb Power Manager

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®4090-3 is a USB power manager plus high voltage Li-Ion/Polymer battery charger.

The device controls 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.
