Features

* s s DESCRIPTIO s s s s s s s s U APPLICATIO S s s s Programmable Charge Current up to 800mA No External MOSFET, Sense Resistor or Blocking Diode Required Constant-Current/Constant-Voltage Operation with Thermal Regulation Maximizes Charge Rate Without Risk of Overheating
* Charges Single Ce

Applications

* Furthermore, the LTC4057 is specifically designed to work within USB power specifications. No external sense resistor is needed and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback prevents overheating by regulating the charge current to limit the die temperat
