LTC4078 - Dual Input Li-Ion Battery Charger

Download the LTC4078 datasheet PDF. This datasheet also covers the LTC4078X variant, as both devices belong to the same dual input li-ion battery charger family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®4078/LTC4078X are standalone linear chargers that are capable of charging a single-cell Li-Ion/Polymer battery from both wall adapter and USB inputs.

The chargers can detect power at the inputs and automatically select the appropriate power source for charging.

Key Features

  • n 22V Maximum Voltage for Wall Adapter and USB Inputs n Charge Single-Cell Li-Ion Batteries from Wall Adapter and USB Inputs n Automatic Input Power Detection and Selection n Charge Current Programmable Up to 950mA from Wall Adapter Input n Overvoltage Lockout for Wall Adapter and USB Inputs n Battery Detection Input Disables Charger When No Battery is Present n No External MOSFET, Sense Resistor or Blocking Diode Needed n Thermal Regulation Maximizes Charge Rate Without Risk of Overheating.
