商品信息

LPSemi/微源半导体 LP28053A ESOP-8 1A单片锂离子和锂聚合物充电器


General Description

The LP28053A is a complete constant-current/constant voltage linear charger for single celllithium-ion battery. Its ESOP8 package and lowexternal component count make the LP28053A ideallysuited for portable applications. No external senseresistor is needed, and no blocking diode is requireddue to the internal MOSFET architecture. Thermalfeedback regulates the charge current to limit the dietemperature during high power operation or highambient temperature. The charge voltage is fixed at4.2V/4.4V, and the charge current can be ISETprogrammed externally with a single resistor.

The LP28053A automatically terminates the chargecycle when the charge current drops to 1/10 settingcurrent value after the final float voltage is reached.When the input supply is removed, the LP28053Aautomatically enters a low current state, dropping thebattery drain current to less than < 1μA.

Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin.


Features

◆ Input Voltage up to 28V
◆ Input Over Voltage Protection:7V
◆ Short-circuit protection
◆ Programmable Charge Current Up to 1000mA
◆ < 1μA Battery Reverse Current
◆ Protection of Reverse Connection of Battery
◆ No MOSFET, Sense Resistor or Blocking Diode Required
◆ Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating
◆ ESOP-8 Package
◆ RoHS Compliant and 100% Lead (Pb)-Free


Applications

◆ Portable Media Players/Game
◆ Power Bank
◆ Bluetooth Applications
◆ PDA/MID
