High-Voltage 950mA Lithium Battery Charger Automatically Selects Between USB or Wall Adapter

Linear Technology Corporation introduces the LTC4075HVX, a standalone dual-input linear battery charger that efficiently manages charging single-cell Li-Ion/Polymer batteries from two separate power sources: a wall adapter and USB. Using a constant-current/constant-voltage algorithm, the charger can deliver up to 950mA of charge current from a wall adapter supply, or up to 850mA of charge current from a USB supply and automatically sense the presence of voltage at each input. The final float voltage accuracy is ±0.6% in either case. The LTC4075HVX provides protection up to 22V(max) on both inputs. If the selected power source exceeds the overvoltage lockout limit, the PVY0722WQM gqqv wkvs vrearzdr.
