Product Overview

The LTC4052EMS8E-4.2#PBF is a Li-ion Battery Pulse Charger with overcurrent protection. It comes as a complete standalone pulse charger with integrated MOSFET for 1-cell Li-ion batteries. An external sense resistor provides overcurrent limiting as a safety precaution against user connecting a wall adapter with the incorrect or no current limit. The internal MOSFET prevents reverse battery current from flowing if the input voltage is shorted to ground, eliminating the need for a blocking diode. As the battery accepts charge and approaches the programmed float voltage, the internal MOSFET begins switching off and on with the duty cycle gradually decreasing as the battery approaches a fully charged condition. A programmable timer terminates the charge cycle. The near end-of-charge C/10 condition is indicated at the CHRG pin when the average charge current falls to one tenth of the wall adapter current.
  • Complete standalone pulse charger for 1-cell Li-ion batteries
  • Requires no microcontroller, MOSFET or blocking diode
