UB2017 Datasheet One-cell Standalone Linear Lithium Battery Charger

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UB2017 ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER CMOS IC.

General Description

UTC UB2017 is a plete, constant current and constant voltage linear charger for single cell lithium-ion batteries.

Its small size and ability to regulate low charge currents make UTC UB2017 especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells.

Furthermore, UTC UB2017 is specifically designed to work within USB power specifications.

Key Features

  • S 54 6 1 23 SOT-26.
  • Programmable Charge Current Up to 500mA.
  • No External MOSFET, Sense Resistor or Blocking Diode Required.
  • Complete linear charger in Thin SOT Package for Single Cell / Coin Cell Lithium-lon Batteries.
  • Constant Current / Constant Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating.
  • Charges Single Cell Li-lon Batteries Directly form USB Port.
  • Preset 4.2V Charge Voltage with High Accuracy about ±1.2%.
