Description
Monolithic Linear Charger

Features

* Preset 4V Charge Voltage with 1% Accuracy Prolongs 4.2V Li-Ion Battery Lifetime
* Automatic Recharge
* Thermal Regulation Maximizes Charging Rate without Risk of Overheating
* No MOSFET, Sense Resistor or Blocking Diode Required
* Programmable Charge Termination Timer

Applications

* By charging to a float voltage of 4V instead of 4.2V or 4.1V, the LTC4064 decelerates the aging process and capacity degradation when the battery is unused for long periods of time but must be in a ready state. An external capacitor programs a safety timer to terminate the charge cycle while the ch
